Last Updated: October 30, 2026

[Latest – October 30, 2026] Samsung States That Its 2027 HBM Supply Has Been Fully Sold; Memory Supply and Demand Expected to Remain Tight in 2028

Confirmed at the October 29, 2026, earnings briefing: Samsung Electronics stated that its 2027 HBM supply has been fully sold out, having concluded negotiations at target prices that reflect the product’s competitiveness. Requests for additional supply from major customers continue to pour in.The company expects memory supply and demand to remain tight in 2028 as well, against the backdrop of rising demand for AI and the difficulty of increasing production in the short term. This reflects Samsung’s sales situation and outlook and does not indicate a shortage across the entire memory market or for all product models.

Confirmed Facts, Manufacturer Outlook, and Unconfirmed Matters

Confirmed: Samsung expanded HBM4 sales in the third quarter of 2026, identifying server DRAM, high-speed DDR5, and server SSDs as key focus areas. In its official financial results, the company forecasts that growth in AI-related memory demand in 2027 will significantly outpace industry supply compared to 2026.
Confirmed at the briefing: It was explained that Samsung’s HBM supply for 2027 has been fully booked, with negotiations concluded at target prices. However, the specific customers, complete product models, quantities, shipment schedules, and contract terms have not been disclosed.
Manufacturer Outlook: Since new capital expenditures do not typically lead to increased production in the short term, Samsung expects the tight memory supply-demand balance to continue into 2028. This is not a definitive guarantee of future shortages.
Unconfirmed: Based on publicly available information alone, it is not possible to verify individual inventory levels, supply allocations, official price increase rates, or confirmed delivery dates for DDR4, DDR5, LPDDR, HBM, and SSDs intended for the Japanese market.

Impact on Japanese Purchasing, Materials, and SCM Personnel

Samsung’s statement that its HBM sales quotas are fully booked through 2027 indicates that securing memory supplies for AI servers has shifted from spot purchases to prioritizing long-term contracts.Since HBM and standard DRAM share some production capacity, there may be indirect supply pressure on server-grade DDR5 and high-capacity RDIMMs as well. However, this does not necessarily mean that SK hynix and Micron are in the same contractual situation.

Actions Procurement Managers Should Take

Organize demand through the first half of 2027 by manufacturer name, full part number, monthly requirement, current inventory, outstanding orders, and desired delivery dates.
Confirm with authorized distribution channels the secured quantities, supply allocations, quote validity periods, price revision conditions, and terms for partial deliveries, changes, and cancellations.
For products designated exclusively for Samsung, verify the availability of certified second sources (such as SK hynix or Micron) and the time required for technical evaluation and customer approval.
When utilizing overseas inventory, verify traceability, manufacturing lots, date codes, storage conditions, and the need for third-party analysis.

Practical Comments from AI Components

You should not rush to purchase all memory simply based on the explanation that “the 2027 supply is already sold out.” It is important to prioritize part numbers significantly affected by the end of mass production, those requiring time for alternative approval, and those with unconfirmed supply quotas, and to individually verify the required quantities and guaranteed delivery dates.At AI Components, we verify supply availability on a case-by-case basis, primarily through authorized distributors.

The following is the update history prior to October 29, 2026.

Last Updated: October 29, 2026

[Latest – October 29, 2026] SK hynix Secures Over 50% of Production Capacity for 2027–2028 Through Long-Term Contracts; Impact on DRAM and HBM Procurement

Firsthand information from the manufacturer announced on October 28, 2026:In its Q3 2026 earnings report, SK hynix announced that it has signed long-term supply agreements (LTAs) with 14 major customers, including cloud service providers, and has secured contracts for volumes equivalent to over 50% of its production capacity for 2027 and 2028.The company also highlighted the expansion of HBM4 shipments and increased sales of DDR5 for servers. Please note that this reflects SK hynix’s specific contract status and does not represent the production capacity of the memory industry as a whole.

Verified Facts and Manufacturer Forecasts

Confirmed: SK hynix’s Q3 2026 revenue was 104.6155 trillion won, and operating profit was 83.3338 trillion won (preliminary figures).Long-term agreements (LTAs) with 14 customers account for over 50% of the company’s production capacity for 2027–2028.
Manufacturer Plans and Outlook: The company expects HBM4 to surpass HBM3E in both shipment volume and revenue in the fourth quarter of 2026 and plans to expand HBM4 production at M15X. It also anticipates that supply and demand tightness may continue through 2030.This is not a definitive guarantee of future shortages.
Remarks from the Earnings Briefing (Confirmed via Media Reports): At the earnings briefing on October 28, the company explained that, when combining existing LTAs with demand currently under specific discussion with customers, it had effectively secured sales outlooks for DRAM and HBM volumes through 2029.This does not mean that “all volumes through 2029 have been contracted” or that “sales inventory for general customers is zero.”
Unconfirmed: Based on publicly available information alone, it is not possible to verify inventory levels for specific part numbers intended for the Japanese market, actual allocation quantities, price adjustment rates, confirmed delivery dates, or order acceptance conditions.

Impact on Japanese Purchasing, Materials, and SCM Personnel

The allocation of production to HBM4 and DDR5 for AI servers, along with the expansion of long-term contracts, could affect not only short-term spot procurement but also mass production plans for 2027.However, do not treat DDR4, DDR5, LPDDR5, RDIMM, and HBM as uniformly scarce items; instead, make judgments based on specific part numbers, customer certifications, quantities, and contract terms. The same contract rates do not necessarily apply to manufacturers other than SK hynix.

Actions Purchasing Managers Should Take Now

Organize planned usage for Q4 2026 through 2027 by complete part number (MPN), monthly usage volume, required quantity, desired delivery date, current inventory, and outstanding orders.
Confirm with manufacturers or authorized distributors whether allocations are available, the quantities secured, quote expiration dates, price revision conditions, and cancellation/change conditions.
If there are certified second-source suppliers such as Samsung or Micron, reconfirm speed, capacity, voltage, temperature grade, package type, PCB and controller compatibility, and customer approval.
When considering overseas procurement, verify traceability, lot numbers, date codes, storage conditions, and the need for third-party analysis.

Practical Comments from AI Components

The key point here is that SK hynix has secured long-term contracts for more than half of its supply capacity for 2027–2028. When procuring memory, rather than “buying in advance because prices are likely to rise,” we recommend prioritizing the part numbers necessary for continued mass production while simultaneously managing supply reliability, required delivery dates, and the timeframe for alternative approvals.We verify procurement feasibility on a case-by-case basis, focusing primarily on official domestic and international distribution channels.

[Latest Information as of 8:55 a.m. on October 23 (Japan Time)] At Micron’s Taoyuan plant in Taiwan, a 24-hour strike by 11 labor union leaders began at 9:00 a.m. on October 22 (Taiwan Time).The strike is scheduled to end at 9:00 a.m. on October 23 (Taiwan Time; 10:00 a.m. Japan Time); as of the time of verification, it has not yet ended.At the Taichung plant, a labor-management agreement was reached on the 21st, and the second round of mediation scheduled for the 22nd was canceled. According to publicly available information we have verified, there are no confirmed impacts on production or shipments. Click here for verified facts and purchasing guidance.

Updated October 23, 2026: 24-Hour Strike at Micron’s Taoyuan Plant—Status as of Before Scheduled End

As of 8:55 a.m. on October 23, 2026 (Japan Time): Taiwan’s Central News Agency reported that 11 labor union leaders at the Taoyuan plant began a 24-hour strike at 9:00 a.m. on October 22 (Taiwan Time).The strike is scheduled to end at 9:00 a.m. on October 23 (Taiwan time; 10:00 a.m. Japan time). At the time of this update, the strike had not yet ended, and the results following its conclusion have not been announced.

Facts Confirmed in Taoyuan and Taichung

In Taoyuan, negotiations between the company and the union failed to reach an agreement, leading 11 union leaders to go on strike. The union stated that it would conduct a survey of its members’ opinions regarding the company’s proposal and decide on its next course of action based on the results. Micron also plans to continue negotiations with the Taoyuan union.

In Taichung, a labor-management agreement was reached on October 21. Consequently, the second round of mediation scheduled for the 22nd did not take place, and the mediation proceedings were withdrawn. The unions in Taoyuan and Taichung are separate entities, and the agreement in Taichung does not imply a resolution to the labor dispute in Taoyuan.

Micron explained that, starting in fiscal year 2027, it will introduce quarterly performance-based compensation for employees worldwide.The compensation is linked to an indicator calculated by subtracting the projected capital expenditures for the following quarter from after-tax profits, and is designed to be paid 50% in cash and 50% in stock that vests after one year.In Taiwan, the company announced an increase in its employer contribution rate for retirement benefits from 8% to 10%, as well as three additional days of paid leave, an increase in shift work allowances, and structural wage adjustments.

Impact on Production and Shipments

Based on publicly available information we have confirmed, there is no confirmed impact on production or shipments. What we have confirmed is a strike by 11 union leaders; it is not a complete shutdown of the Taoyuan plant.We have also found no public announcements indicating changes in DRAM or HBM production volumes, shipment quantities, or the prices and delivery times of specific models. We cannot definitively state that there is “no impact”; it will be necessary to confirm announcements from the company and the union, as well as supply responses, once the strike concludes.

Impact on Procurement and Actions for Purchasing Personnel

Please cross-check the BOM for Micron-specified items against the exact part numbers, required quantities, current inventory, and outstanding orders, and confirm with authorized sales channels whether quantities have been secured and if there have been any changes to delivery schedules. Confirm the conditions for switching to approved alternatives with the design and quality departments.For overseas inventory, verify authenticity, manufacturing lot, date code, traceability, and storage conditions.

After the strike ends, verify the results of the Taoyuan Labor Union’s opinion survey, the status of negotiations with the company, and Micron’s explanation regarding production and shipping. It is important to distinguish between overall market DRAM supply and demand and this labor-management issue, and to evaluate supply responses on a part-number-by-part-number basis.

Practical Comments from AI Components

The situation has shifted from “a planned strike” to “a strike carried out by 11 union leaders.” However, there have been no confirmed reports of a complete factory shutdown or supply disruptions. We recommend against rushing to purchase based solely on media reports; instead, verify the reliability of supply and the feasibility of alternatives, starting with Micron-specified products critical to continued mass production.

Procurement Consultation with Specific Part Numbers and Quantities

Updated October 21, 2026: DRAM Contract Prices for 4Q26 Expected to Rise Approximately 20% Quarter-Over-Quarter

A new forecast has been reported indicating that DRAM contract prices for the fourth quarter of 2026 are expected to rise by approximately 20% compared to the previous quarter. This is driven by expanding demand for AI inference and limited increases in the supply of mature-generation memory.

However, this “approximately 20%” figure does not represent a confirmed price increase rate for individual part numbers. As of September 30, TrendForce’s research division had projected a 10–15% increase for conventional DRAM compared to the previous quarter.The October 20 article presents a market outlook based on reports from sources such as the Commercial Times; it is important to distinguish between the source of the forecast and the date of its publication.

Confirmed Facts and Market Outlook

An article published by TrendForce News on October 20 reported that, according to institutional investors, DRAM contract prices in Q4 2026 are expected to rise by approximately 20% quarter-over-quarter.The rate of increase is expected to slow from approximately 80% in the second quarter of 2026 and approximately 40% in the third quarter. Actual fluctuation rates will vary depending on the basis of comparison, contract terms, and product mix.

The article cites the expansion of AI inference, demand for high-capacity server DRAM and enterprise SSDs, and limited increases in the supply of mature-generation memory as factors supporting prices. On the other hand, it also suggests that declining purchasing power among customers and price caps imposed by long-term contracts could temper the rate of increase.

Impact on Procurement

Rather than treating DDR4, DDR5, RDIMM, LPDDR, and other products as a single category, it is necessary to confirm quotes, supply allocations, and delivery dates for each specific part number. It is not possible to assume that all products will increase in price by the same percentage based solely on the forecast of an approximately 20% increase for the overall market.

Please assess the labor-management dispute at Micron Taiwan separately from supply risks in the DRAM market. As of October 21, publicly available information indicates that no actual production stoppages or shipment delays resulting from this dispute have been confirmed.

Actions Purchasing Managers Should Take

Compile a list of the DRAM required to maintain mass production, including specific part numbers, monthly usage volumes, current inventory levels, and outstanding orders.
Confirm with suppliers the validity period of quotes, timing of price revisions, supply allocations, guaranteed quantities, and NCNR terms.
Verify the status of technical evaluations and customer approvals for certified alternatives from Micron, Samsung, SK hynix, and others.
When utilizing overseas inventory, verify the date code, manufacturing lot, traceability, storage conditions, and authenticity.

Practical Comments from AI Components

The figure of approximately 20% mentioned here serves as a basis for reviewing procurement plans, but it does not represent a fixed price for individual part numbers. It is important not to decide on advance purchases based solely on the rate of price increase; instead, make decisions by considering the risk of mass production discontinuation, supply reliability, and the time required for alternative approval.

Updated October 22, 2026: Micron’s Taichung plant reaches labor-management agreement; Taoyuan plant plans 24-hour strike

As of 8:30 a.m. on October 22, 2026 (Japan Time): The labor union at Micron’s Taichung plant in Taiwan reached an agreement with the company on October 21 and withdrew its request for mediation on the 22nd.Meanwhile, a separate union at the Taoyuan plant is planning a 24-hour strike starting at 9:00 a.m. on October 22 (Taiwan time; 10:00 a.m. Japan time). Actual production stoppages or shipment delays have not yet been confirmed.

Amid ongoing supply constraints for DRAM and HBM, the labor-management agreement in Taichung is a factor indicating a reduction in risk. However, the Taoyuan plant faces a separate labor-management issue. As of the morning of October 22, no production stoppages or shipping delays resulting from this issue have been confirmed. Inventory levels, prices, and delivery times also remain unconfirmed on a part-number-by-part-number basis.

Facts Confirmed by Media Reports

On October 7, the labor union at the Taoyuan plant announced that it had secured the right to strike following a vote by union members. According to the Central News Agency (CNA), 1,994 out of 2,012 voters voted in favor. Subsequently, the union announced plans to hold a strike on October 22.

At the Taichung plant, a labor-management agreement was reached on October 21, and the mediation scheduled for October 22 was withdrawn. The details of the agreement have not been disclosed. Meanwhile, the union at the Taoyuan plant is maintaining its plan to hold a 24-hour strike on the 22nd. The two plants are represented by separate unions.

The main points of contention are the profit-sharing system and bonuses for employees. In a response to media inquiries, Micron stated that it respects employee rights and is committed to continuing constructive dialogue with both unions.

Impact on Supply Chain and Unconfirmed Matters

Taiwan is a key hub for Micron’s DRAM and HBM production. The Taoyuan plant is primarily involved in DRAM wafer front-end processes, while the Taichung plant handles advanced DRAM and HBM manufacturing and back-end processes.TrendForce analyzes that if the Taoyuan strike ends within one day and maintenance and process monitoring are maintained, the impact on supply could be limited. This is a conditional outlook, and no actual production disruptions have been confirmed.

It is not appropriate to predict a complete halt in the supply of Micron’s DRAM and HBM or price increases based solely on this incident. Supply conditions for specific part numbers must be confirmed with the manufacturer or authorized sales channels.

Actions Purchasing Managers Should Take

Review the BOMs that use Micron DRAM to confirm the exact part numbers, required quantities, current inventory levels, and outstanding orders. For part numbers critical to continued mass production, contact the manufacturer or authorized sales channels to inquire about secured quantities and future shipment schedules.

If certified alternatives from Samsung Electronics, SK hynix, or other manufacturers are available, please reconfirm the conditions for switching to these alternatives and the status of customer approval. When utilizing overseas inventory, it is also important to verify the date code, manufacturing lot, traceability, storage conditions, and authenticity.

We recommend reviewing the status of the strike at the Taoyuan plant on October 22, the operational status of the Taichung plant following the agreement, and the manufacturer’s explanations regarding production and shipments, and revising your procurement policy based on the actual impact on supply.

Practical Comments from AI Components

We note that new uncertainties have emerged in the DRAM market, where supply constraints persist. However, we do not recommend large-scale preemptive purchasing based solely on strike plans.

Rather than searching for inventory after production halts occur, it is important to understand the current supply situation and potential alternatives in advance. Particularly for products designated exclusively from Micron, please clarify the required quantities, desired delivery dates, and availability of alternatives to confirm supply conditions.

Update as of October 12, 2026: 2027 DRAM and SSD Prices and BOM Cost Measures

Due to growing demand for AI servers, supply constraints for semiconductors—particularly DRAM—are likely to persist into 2027.A market survey by TrendForce published on October 8, 2026, projected that rising prices for CPUs, DRAM, and SSDs will drive up manufacturing costs for finished products and impact notebook PC shipments in 2027.

This is information that companies procuring industrial PCs, embedded systems, and inspection equipment should also keep a close eye on. However, supply-and-demand forecasts for consumer PCs do not necessarily apply directly to components for industrial equipment.

Confirmed Facts and Market Forecasts

According to the October 8 report, for a mainstream laptop with a manufacturer’s suggested retail price (MSRP) of $900, it is estimated that CPUs, DRAM, and SSDs will account for approximately 68% of the total bill of materials (BOM) cost in the third quarter of 2026.This 68% figure represents the proportion of the bill of materials (BOM) cost, not the percentage of the finished product’s selling price.

The same survey predicts that global notebook PC shipments in 2027 will decline by a few percent year-over-year. If the increase in component prices is passed on to the selling price to a significant extent, the decline could be even greater.

Additionally, according to TrendForce’s contract price forecast for the fourth quarter of 2026, released on September 30, conventional DRAM is expected to rise by 10–15% quarter-over-quarter, and NAND Flash by 15–20%. These are forecasts for the overall market and do not represent final prices for specific part numbers.

Impact on Procurement

When planning procurement for 2027, it is important to distinguish between price increases and supply shortages. For DRAM, the continued allocation of production capacity to AI servers may limit the expansion of supply for PC-oriented products.

On the other hand, TrendForce points out that new production capacity for NAND Flash is expected to come online in the second half of 2027, which could alleviate supply constraints. It is necessary to examine the outlook for each product segment separately, rather than treating DRAM and NAND as a single category.

For PCBs, MLCCs, and PMICs as well, raw material costs and the allocation of production capacity may put pressure on prices and delivery times. However, it has not been confirmed that all products will see price increases or extended lead times.

Actions Procurement Managers Should Take

First, identify the specific DRAM, NAND, and SSD models scheduled for use in 2027 by exact part number, and organize the monthly usage volume, current inventory, outstanding orders, and required delivery dates.

Next, contact manufacturers or authorized sales channels to confirm 2027 supply allocations, quote validity periods, standard lead times, price protection, and cancellation terms.

For products specified from a single manufacturer, it is important to expedite the evaluation of alternative candidates. Even if DRAM has the same capacity and speed, you must verify the package, operating voltage, temperature grade, and compatibility with the controller.

When utilizing overseas inventory, prioritize traceability, date codes, storage conditions, and authenticity verification.

Practical Comments from AI Components

We are noting that rising semiconductor prices are now reaching a stage where they are impacting the manufacturing costs and sales plans of finished products. However, the future supply outlook differs between DRAM and NAND.

Rather than purchasing all memory modules in advance across the board, we recommend verifying supply reliability starting with part numbers at high risk of production discontinuation and securing the necessary quantities.

Previous Updates and Market Information

Against the backdrop of growing demand for AI servers, supply constraints for DRAM, HBM, and NAND are becoming prolonged.On September 30, 2026, TrendForce forecast that contract prices for conventional DRAM in the fourth quarter of 2026 (4Q26) would rise by 10–15% quarter-over-quarter, while NAND Flash contract prices would increase by 15–20%.Supply shortages for server DRAM are expected to persist through 4Q26.Micron Technology has also indicated that the supply-demand balance for memory and storage in 2027 and 2028 will be even tighter than in 2026. In this article, we will categorize primary information, market research, and forecasts, and outline the measures that electronics manufacturers, EMS providers, and procurement managers should take.

Updated October 1, 2026: Micron Predicts Supply Constraints for DRAM and NAND Will Continue Through 2027–2028

Verified Facts: In its September 30 earnings presentation materials, Micron indicated that the supply-demand balance for memory and storage in 2027 and 2028 will be “much tighter” than in 2026.Regarding DRAM, the company forecasts that industry-wide bit shipments will grow in the low 20% range in both 2027 and 2028, while supply constraints are expected to persist in both years. For NAND, the company anticipates that industry-wide bit shipments will grow in the mid-20% range during the same period, while supply constraints are expected to continue.

Micron also expects HBM bit shipments to grow faster than traditional DRAM through 2028.Regarding HBM supply in 2027, the company explains that it has already finalized contracts with customers for the majority of its bit supply, and that these contracts involve significant price increases compared to the previous year. This reflects Micron’s specific contract situation and does not imply that the entire supply for the HBM market has been reserved.

In terms of pricing, Micron reported that in Fiscal Q4 2026, DRAM prices rose by high-teens percent quarter-over-quarter, while NAND prices rose by approximately 30 percent. These figures reflect Micron’s actual results and do not indicate that the same rate of increase will apply to all manufacturers, models, or regions.

Micron Primary Information	Implications for Procurement
Supply constraints for DRAM and NAND are expected to continue through 2027–2028	Confirm required quantities and supply allocations not only for the first half of 2027 but also for the medium to long term
The majority of HBM supply for 2027 has already been contracted	For AI and server applications, contracts and allocations are becoming more important than securing spot purchases
It will take time for new DRAM/NAND fabs to contribute to supply	We will not reduce short-term safety stock solely based on new fab plans
DRAM and NAND prices rose in Q4	Verify quote validity periods, price protection, and NCNR terms on a part-number basis

Impact on Procurement

DRAM: For DDR5, high-capacity RDIMMs, LPDDR-series products, and others, securing allocations and delivery dates is becoming increasingly important, in addition to price.
HBM: Since a significant portion of the 2027 supply is tied to long-term contracts, it is crucial to confirm supply quotas on a per-customer and per-platform basis for AI server projects.
NAND: Due to strong demand for enterprise SSDs for AI, supply priorities may shift, particularly for high-capacity products intended for data centers. For details, please also refer to the article on tight enterprise SSD and NAND supply.
Previous-Generation Products: As investment and production allocation continue to shift toward high-value-added products, it is necessary to separately confirm the continued availability of previous-generation DRAM and NAND.

Actions Procurement Personnel Should Take

Re-confirm demand for the first half through the second half of 2027 by manufacturer name, full part number, and quantity.
Confirm with manufacturers or authorized channels the secured quantities, supply allocations, shipment schedules, price validity periods, and NCNR terms.
For products designated exclusively from Micron, verify the availability of certified second sources (such as Samsung and SK hynix) and the customer approval period.
When using overseas inventory, verify the date code, lot number, traceability, storage conditions, and authenticity verification requirements.
For HBM and high-capacity products for servers, confirm with Sales and SCM whether long-term supply quotas are available, in addition to spot inventory.

Practical Comments from AI Components

This announcement from Micron is significant in that it goes a step further than the conventional market forecast of “supply remaining tight through 2027,” with the manufacturer itself explicitly stating that supply constraints will continue through both 2027 and 2028. However, not all DRAM, NAND, and HBM products will have the same lead times or the same rate of price increases.Rather than rushing to make purchases, we recommend prioritizing part numbers critical to maintaining mass production and verifying the required quantities, desired delivery dates, and availability of alternatives on a part-by-part basis.

Updated September 29, 2026: HBM Expansion Puts Pressure on Standard DRAM Supply Capacity

Confirmed fact: Kim Taewoo of Samsung Electronics explained that HBM is projected to account for approximately 30% of the entire DRAM industry’s wafer capacity in 2027, up from the current level of about 20%.Since HBM and standard DRAM utilize the same wafer capacity, the expansion of HBM production could constrain the supply capacity for standard DRAM.

Market Outlook: TrendForce forecasts that the blended ASP for HBM in 2027 will rise 121% year-over-year, driven by supply constraints, an increase in the HBM4 mix, and the launch of HBM4E. This does not mean that the price of any single product will uniformly increase by 121%.

Impact on Procurement

If production is increasingly allocated to HBM, it could put pressure on the supply capacity of standard DRAM products such as DDR5, RDIMM, and LPDDR5X.
With the generational transition to HBM4 and HBM4E coinciding with demand for AI servers, securing supply and price negotiations are expected to remain critical in 2027.
Since we have not confirmed specific delivery delays across all manufacturers and model numbers, it is necessary to verify each MPN individually.

Actions Purchasing Managers Should Take

Re-confirm demand through the first half of 2027 by manufacturer name, full model number, and quantity unit.
Confirm supply allocations, quote validity periods, scheduled shipment dates, and cancellation terms with suppliers.
For items specified from a single manufacturer, expedite the technical evaluation of alternative candidates and obtain customer approval.
When utilizing overseas inventory, verify the manufacturing lot, date code, traceability, storage conditions, and authenticity verification procedures.

Practical Comments from AI Components

The key point here is that it has become clearer that the expansion of HBM demand is not merely an issue specific to HBM itself, but also affects the production capacity for standard DRAM. On the other hand, it is not yet possible to conclusively state that there will be a uniform shortage of all DRAM products or that prices will rise at the same rate across the board.We recommend prioritizing part numbers critical to continued mass production and verifying each one individually based on model number, quantity, desired delivery date, target price, and availability of alternatives.

Confirmed Facts

According to a DRAM market survey published by TrendForce on September 7, 2026, DRAM industry revenue for the second quarter of 2026 reached approximately $154.73 billion, a 59.5% increase from the previous quarter.In addition to rising contract prices for conventional DRAM, increased shipments of HBM3e, LPDDR5X, and high-capacity RDIMMs for AI servers are supporting the revenue growth.

The survey indicates that inventory levels among major suppliers are at historically low levels, and much of the additional supply is being allocated to server applications. Growth in DRAM bit shipments has been limited, and supply expansion has not kept pace with rising demand.

Furthermore, in its third-quarter fiscal 2026 earnings report, Micron announced that it has begun mass-producing and shipping HBM4 to major customer platforms, with mass production of HBM4E scheduled for 2027.On September 8, 2026, Samsung also announced an expansion of its collaboration with ASML and outlined plans to introduce High NA EUV for future DRAM manufacturing. These developments indicate that companies are prioritizing investments in high-performance memory for AI and next-generation DRAM.

Additional Confirmation as of September 14, 2026

According to a TrendForce survey released on September 9, the combined revenue of the world’s top 10 foundries in the second quarter of 2026 reached approximately $53.49 billion, an 11.5% increase from the previous quarter.In addition to supply constraints for advanced processes for AI/HPC, increased demand for peripheral devices such as PMICs and power discrete components is cited as a growth factor. This indicates that the impact of AI demand is spreading not only to HBM and GPUs but also to power and peripheral semiconductors.

Additionally, on September 10, Reuters reported that various Chinese AI accelerator manufacturers had raised prices on some products amid the HBM shortage. Since this is not based on official manufacturer price lists, we do not treat it as definitive pricing information for individual products but rather as secondary data indicating tensions in market supply and demand.

Meanwhile, TSMC announced on September 10 that its revenue for August 2026 was NT$514.81 billion, a 53.3% increase year-over-year, while cumulative revenue for January through August rose 39.3% compared to the same period last year.Although TSMC itself does not disclose the factors behind its monthly sales by product, this is primary information confirming that demand for cutting-edge semiconductors remains at a high level.

Added September 16, 2026: Labor-Management Issues at Micron’s Taiwan Facility and Supply Risks

Confirmed facts: On September 15, 2026, Reuters and other media outlets reported that a labor union at Micron’s Taiwan facility is demanding a permanent profit-sharing system and may proceed with a strike vote if no progress is made during negotiations on September 18 and 21.Taiwan is a key hub for Micron’s DRAM and HBM production. However, as of now, there is no confirmed information that a strike will take place or that production will be halted.

Additionally, on September 15, Micron announced the successful demonstration of what it claims is the world’s first 512GB DDR5 RDIMM for next-generation servers.Designed to operate at up to 9,200 MT/s and enable a single 24-slot, dual-socket server to accommodate up to 12 TB of DDR5, mass production is scheduled for the second half of 2027. AMD and Intel are currently validating the technology for their next-generation server platforms.

Impact on Procurement

DRAM/HBM: If labor-management negotiations drag on, it could add new uncertainty to an already tight memory supply.
Server DDR5: This new development indicates continued demand for high-capacity DRAM for AI and HPC, and production and investment allocations may continue to prioritize high-capacity products.
Purchasing Practices: For Micron-specified or single-source items, it is time to reevaluate not only current inventory levels but also required quantities for the next 3 to 6 months, the availability of alternatives, and certified second sources.

Actions Procurement Personnel Should Take

Identify BOMs that use Micron’s DRAM, DDR5, and HBM-related products, and reconfirm the required quantities and desired delivery dates for each part number.
Confirm with suppliers not only their response lead times but also their secured inventory, backorders, cancellation terms, and price validity periods.
For parts that can be substituted, expedite technical evaluations of potential second-source candidates, including Samsung and SK hynix.
When utilizing the spot market, verify the lot, manufacturing date, traceability, storage conditions, and authenticity verification requirements.

Practical Comments from AI Components

The current labor-management issue does not constitute a “supply stoppage” at this time. Therefore, you should not engage in excessive preemptive purchasing based solely on uncertainty. However, there is a possibility that labor risks at the Taiwanese facility could compound the structural supply-demand tightness caused by production capacity shifting toward HBM and high-capacity DDR5.For Micron-specified products where approval for substitutes takes time, it will be too late to act once the problem becomes apparent; therefore, we recommend confirming options based on part numbers, quantities, and desired delivery dates as early as possible.

Added September 17, 2026: DRAM supply constraints may continue into 2027

Confirmed facts: In its March 2026 earnings presentation, Micron indicated that DRAM and NAND demand in 2026 would be constrained by supply limitations and projected that tight supply-demand conditions would persist beyond 2026.Furthermore, TrendForce predicts that from late July through August 2026, DRAM supply will remain tight in 2027 as well, driven by AI demand.

While investments to increase production are underway on the supply side, this does not necessarily mean that spare capacity will increase significantly in the short term. SK hynix announced a major investment in new factories for DRAM and NAND in August 2026, but the M17 cleanroom is scheduled to begin operations in December 2028, and the Y2 facility in June 2029.Therefore, this investment is a measure to strengthen supply capacity over the medium to long term and will not immediately ease the supply-demand situation in 2026–2027.

Impact on Procurement

DRAM: Focusing primarily on DDR5, high-capacity RDIMMs, and server-grade products, the ability to “secure the required quantities”—not just price—may become a key factor.
HBM: If production continues to be allocated toward high-value-added products for AI servers, the structural pressure on the supply capacity of general-purpose DRAM will persist.
NAND: While the situation is not as uniform as with DRAM, differences between products may widen depending on manufacturers’ allocation of production capacity and demand for AI storage.

Actions Procurement Professionals Should Take

Confirm demand volumes by major MPN not only for the end of 2026 but also through the first half of 2027.
Verify not only quoted prices but also secured quantities, supply allocations, shipment schedules, and NCNR terms.
For products specified from a single manufacturer, begin technical evaluations of alternative candidates and seek customer approval as early as possible.
When utilizing overseas inventory, verify the manufacturing lot, traceability, storage conditions, and authenticity verification requirements in advance.

Practical Comments from AI Components

The key point here is that this is not merely a phase of price increases; it has become necessary to formulate procurement plans based on the assumption that supply constraints will continue through 2027. However, not all DRAM and NAND products will experience the same delivery times or price increases.In practice, it is important to verify the manufacturer name, part number, quantity, desired delivery date, target price, and availability of alternatives on a per-part-number basis to increase supply reliability while avoiding excessive advance purchases.

Added September 19, 2026: Labor-management negotiations at Micron Taiwan continue; no production stoppages have been confirmed at this time

Confirmed facts: Micron and the Taiwan Micron Memory Workers’ Union held their first labor-management mediation session on September 18, discussing compensation and bonus systems, the “No Free Rider” policy, and non-retaliation measures. Both parties agreed to continue discussions and hold the next mediation session on October 22, 2026.As of now, there is no confirmed information regarding a strike or a halt in DRAM or HBM production.

Impact on Procurement

Short Term: Since no production stoppages have been confirmed at this time, we do not recommend excessive emergency purchasing based solely on labor-management issues.
Medium Term: As the negotiations remain unresolved, labor risks associated with Micron-specified and single-source products must be continuously monitored until the next round of negotiations on October 22.
Overall Supply and Demand: Given that the DRAM and HBM markets themselves have limited supply capacity due to demand for AI servers, a further escalation of labor issues could exacerbate the existing supply-demand tightness.

Actions Purchasing Personnel Should Take

Confirm the required quantities, desired delivery dates, and availability of alternatives for Micron products by major MPN.
For part numbers critical to continued mass production, confirm with suppliers the quantities already secured, outstanding orders, and scheduled shipments.
If there are approved secondary sources, such as Samsung or SK hynix, reconfirm the conditions for switching and the approval status.
Until the results of the next meeting on October 22 are available, regularly check inventory, prices, and delivery dates, and do not rush into purchases based solely on unconfirmed information.

Practical Comments from AI Components

The key point in this September 19 update is not that “a strike has occurred,” but rather that discussions are ongoing and no production stoppage has been confirmed at this time. In procurement practice, it is important not to make decisions on advance purchases based solely on news headlines, but to verify supply reliability based on part numbers, quantities, desired delivery dates, target prices, and the availability of alternatives.On the other hand, structural supply constraints for DRAM and HBM remain a separate risk, so you should not stop evaluating second-source options for BOMs with high dependence on Micron.

Future Price Outlook

Next, we’ll look at the market outlook. TrendForce forecasts that for the fourth quarter of 2026, contract prices for conventional DRAM will rise by 10–15% quarter-over-quarter, while prices for NAND Flash as a whole will increase by 15–20%.Supply shortages are expected to persist for server DRAM, while prices for enterprise SSDs are projected to rise at a faster pace than in the previous quarter due to expanding demand for AI inference and agentic AI.

Looking ahead to 2027, TrendForce anticipates that HBM and conventional DRAM will compete for limited cutting-edge process and wafer capacity, and that HBM supply constraints will persist.The blended ASP for HBM in 2027 is forecast to rise 121% year-over-year; however, this is an average figure that includes changes in product mix and does not mean that specific HBM part numbers will uniformly increase in price by 121%.

Impact on Procurement

Price: Price increases may be reflected in new or updated quotes. Particular attention should be paid to DDR5, high-capacity RDIMMs, and AI and server-related products.
Delivery Times: As demand for servers takes priority, longer lead times and allocation-based sales may occur for certain product types.
Inventory: While excess inventory should be avoided, if safety stock levels are low for products in continuous mass production, it is time to reconfirm required quantities and delivery dates.
Alternatives: Even for products with the same capacity and specifications, compatibility may vary depending on the manufacturer, speed, temperature grade, and packaging conditions; therefore, prior evaluation is necessary.

Actions Purchasing Personnel Should Take

Re-confirm demand forecasts for the next 3 to 6 months and DRAM usage by BOM.
For products in ongoing mass production, verify the quote validity period, delivery date responses, and price protection conditions for each supplier.
For part numbers dependent on a single manufacturer, expedite technical evaluations of second-source or alternative candidates.
When utilizing the spot market, be sure to verify traceability, manufacturing lots, storage conditions, and authenticity verification procedures.
Make decisions based on total procurement costs—including not only price but also supply reliability and delivery risk.

Practical Comments from AI Components

The current memory market situation is not simply a matter of “buying in bulk because prices are rising.” Supply priorities for individual products are shifting due to demand for AI servers, so even for the same type of DRAM, supply and demand conditions vary by part number. In practice, it is important to prioritize the quantities necessary for continued mass production and to verify price, delivery time, and substitution options on a part-by-part basis.

In particular, if you start looking for alternatives only after lead times begin to lengthen, it will take time to conduct technical evaluations and obtain customer approval. For critical BOM items, we recommend identifying potential alternatives and overseas inventory sources before supply risks become apparent.

Frequently Asked Questions

Will there be a shortage of all DRAM in 2027 and 2028?

No. While Micron has indicated that supply constraints are expected to persist across the industry as a whole, actual lead times and inventory levels vary depending on the DDR generation, capacity, speed, temperature grade, manufacturer, and customer contracts. Verification by exact part number is required.

Is all HBM for 2027 already sold out?

We cannot say that with certainty. While Micron has stated that it has finalized contracts for the majority of its 2027 HBM bit supply, this reflects Micron’s specific supply situation and does not represent the entire HBM market.

Should we build up large inventories now?

We do not recommend blanket pre-purchases. You should prioritize part numbers critical to continued mass production, single-source parts, and part numbers that require time for alternative approval. You should then determine your safety stock levels after confirming demand volumes, supply allocations, and pricing terms.
