first_img SK Hynix accelerates the expansion of its 1c DRAM market share, becoming the main force by early next year

According to the Chosun Ilbo report on September 7, SK Hynix is accelerating the increase of the production share of 10-nanometer sixth-generation (1c) DRAM. Industry data shows that its 1c DRAM share rose from about 10% in the first quarter of this year to about 13% in the second quarter, and is expected to reach about 24% in the third quarter and about 34% in the fourth quarter; it may rise to about 35% in the first quarter of next year, surpassing 1b (about 33%) for the first time and becoming the main process. The share of 1b (10-nanometer fifth-generation) DRAM peaked at about 43% in the second quarter of this year and has since begun to decline.By the end of the second quarter, Samsung Electronics had a 1c share of about 16% and Micron about 19%, both higher than SK Hynix's approximately 13%. Reports indicate that SK Hynix is accelerating the transition in the second half of the year, and in the fourth quarter, it may exceed Samsung Electronics' approximately 31% with about 34%. SK Hynix stated in its second-quarter earnings call that the supply of DRAM using the 1c process will substantially begin from the second quarter, and in the second half of the year, with the ramp-up of HBM4 and increased shipments of 1c general DRAM, the bit growth rate will be higher than in the first half.Samsung Electronics will use 1c DRAM starting with HBM4, with a running speed of about 11.7Gbps; SK Hynix previously prioritized ensuring mass production stability with verified 1b DRAM and advanced MR-MUF packaging, and will use 1c DRAM for the first time as the core chip for HBM starting with the next generation HBM4E. Counterpoint Research and others estimate that this year, the market share of HBM4 under the combined metrics of Nvidia, Google, and AMD is approximately 50% for SK Hynix in the mid-range, 20% for Samsung Electronics in the later range, and 10% for Micron in the later range.

first_img Micron plans to expand HBM production capacity to approximately 100,000 wafers per month by the end of the year

According to Electronic News on September 3, Micron plans to double its high bandwidth memory (HBM) production capacity compared to last year, with a maximum addition of 60,000 wafers per month by the end of this year. Insiders say that Micron's HBM output was about 40,000 to 50,000 wafers per month last year, and it is expected to reach about 100,000 wafers per month by the end of the year, narrowing the gap with Samsung Electronics and SK Hynix.Micron is increasing procurement orders from multiple HBM equipment suppliers, with production bases mainly in Taiwan and Singapore, continuously introducing equipment. Currently, the output is mainly HBM3E 12-layer, with HBM4 12-layer accounting for about 20% to 30% at the beginning of this year, which may rise to as high as 50% by the end of the year. HBM4 12-layer will be used in NVIDIA's latest AI accelerator, Vera Rubin, and Micron has started mass production of this product since the second quarter of this year.Micron CEO Mehrotra stated in the Q3 earnings call for fiscal year 2026 in June this year that the ramp-up speed of HBM4 12-layer mass production is about twice that of HBM3E 12-layer, and cumulative revenue from HBM4 shipments has exceeded $1 billion. The industry believes that Samsung and SK Hynix each have HBM production capacities of about 150,000 to 200,000 wafers per month. Counterpoint data shows that in Q2 of this year, the global HBM market shares were SK Hynix 50%, Samsung 32%, and Micron 18%. Micron is also preparing related investments in Hiroshima, Japan.

hot_img Micron will issue the highest performance bonuses in history to avoid worker strikes

According to Reuters, Micron Technology's unions in Taoyuan and Taichung, Taiwan are preparing for a strike. The union claims to represent nearly 10,000 of Micron's approximately 15,000 employees in the two locations, and an internal survey shows that over 80% of members support the strike. The core of the labor dispute revolves around bonus distribution— the union believes that the current incentive plan does not adequately reflect the company's profitability and is demanding a one-time additional bonus for this fiscal year, as well as a shift to quarterly profit sharing of 15% of operating profits starting from the 2027 fiscal year. Micron previously responded that it would issue the highest performance bonuses in history, but the union believes the company has not adequately explained the performance calculation method, and it seems to be more closely tied to revenue rather than profit.As the world's third-largest memory chip manufacturer, Micron reported revenue of $41.46 billion and a net profit of $28.24 billion in the third fiscal quarter, with a market capitalization of approximately $1.1 trillion. Taiwan is Micron's largest manufacturing base, with a cumulative investment of NT$1.4 trillion, producing DRAM and HBM. If the strike proceeds, it may impact the global memory chip supply. The Taichung Science Park Administration stated that it is closely monitoring the situation and has prepared a labor mediation mechanism. Previously, the Samsung union also raised similar profit-sharing demands and obtained a special bonus pool of 10.5% of the chip division's operating profits after negotiations.

first_img Micron warns that AI storage walls are intensifying, with HBM accounting for about 17% of the interruptions in Meta Llama 3 training

According to TrendForce, at Hot Chips 2026, Micron emphasized that the progress of AI computing power is faster than storage improvements, and the challenge of the "storage wall" is becoming increasingly prominent. Micron Fellow Raghu Sriramaneni pointed out that the computing power of AI accelerators increases approximately threefold every two years, while the bandwidth of HBM increases by less than double during the same period, and the gap may further widen. The deepening reliance on HBM also brings reliability issues; Micron cited Meta Llama 3 data indicating that HBM failures account for about 17% of unexpected training interruptions. New designs that blur the boundaries between computing and storage may help break through the bottleneck.The expansion of HBM also brings area and supply pressures: the latest generation of packaging integrates two GPUs with eight 12-layer HBM4 stacks, with storage accounting for about 90% of the semiconductor area, more than eight times the area occupied by GPUs; achieving equivalent capacity with HBM requires about three times the wafers of standard DDR5 DRAM. Thermal management has also become a key constraint, with solutions such as liquid cooling and ultra-thin chips being explored.Micron is advancing innovations in interconnect, packaging, and cooling, including SerDes and die-to-die PHY optimized for storage, larger size SiP and advanced packaging with glass substrates, as well as liquid cooling and hybrid bonding, and is developing fusion bonding to reduce thermal resistance and enhance data throughput.

hot_img Micron: The value of memory in the system has increased from 10% to nearly 50%, and the demand for AI agents is in the "pre-season warm-up" stage

Micron Technology stated to Deutsche Bank at the FMS 2026 conference that AI is reshaping the memory industry landscape, with the proportion of memory in the total value of systems rising from about 10% thirty years ago to nearly 50% currently, and this trend is accelerating. Currently, both DRAM and NAND are in a state of supply shortage. Due to the need for physical disassembly of systems for memory upgrades, the demand for memory in AI systems is more rigid, and price elasticity is lower than market expectations. The Strategic Customer Agreement (SCA) is expected to cover about 40% of sales, providing a price stability mechanism for both parties.Micron's management described the demand for CPU-side AI Agents as "pre-season warm-up," viewing it as a new pillar of growth outside the GPU ecosystem. For emerging technologies like SRAM, Micron believes their scalability is limited and cannot challenge the core position of HBM, with only about 5% of systems currently running such specific workloads. Deutsche Bank maintains a "Buy" rating, believing Micron has a unique advantage of "growth without sacrificing profits." During FMS, Sandisk and SK Hynix jointly released the first HBF technical specifications, but Micron believes that its actual value and commercialization prospects remain controversial.

hot_img Silicon wafer supply tightens: 12-inch capacity is nearing full load, GlobalWafers signs a 10-year contract with Micron

According to the South Korean media The Elec, GlobalWafers stated during the Q2 earnings call that the production lines for 12-inch, 8-inch, and 6-inch wafers are nearing full capacity, with some advanced 12-inch products experiencing supply constraints due to a surge in demand for AI chips, HBM, and advanced packaging. Shin-Etsu Chemical achieved double-digit growth in 12-inch shipments both year-on-year and quarter-on-quarter in Q2, and Sungrow also believes that customer inventory adjustments are nearing completion. Although SK Siltron is gradually releasing capacity from new production lines, it is still difficult to meet the growth rate of orders.Tight supply is driving changes in long-term contract models, and GlobalWafers signed a 10-year LTA (including advance payment) with Micron last month. Prices in the non-LTA market have begun to rise and are expected to continue to increase in the second half of the year. GlobalWafers stated that it is negotiating with customers to incorporate price adjustment mechanisms into new contracts, and Nexchip also emphasized the need for "broad and meaningful price increases" to support reinvestment. Industry insiders expect that as new factories from Samsung, SK Hynix, and Micron come online, wafer demand will double in the second half of 2027, and supply shortages may further intensify.
