AI-Driven Storage Chip Shortage Intensifies

　　Recently, the global memory chip industry has shown strong momentum, with the market continuing to rise amid volatility driven by the AI computing boom and structural capacity constraints. The industry widely believes that the imbalance between supply and demand, along with rising prices, will persist, keeping the memory chip sector in a high-growth phase.

　　Micron Executives Call Memory Shortage “Unprecedented,” Pursue Dual-Track Expansion to Address Gap
　　Recently, Micron Technology broke ground on a massive $100 billion wafer fabrication plant in Onondaga County, New York. The facility is expected to begin production in 2030 and gradually ramp up to full capacity over the following decade, becoming a cornerstone of Micron’s strategy to address the global memory chip shortage. On the day after announcing the new fab, Micron made another major move—acquiring Powerchip Semiconductor Manufacturing Corporation’s (PSMC) P5 wafer fab and associated infrastructure in Tongluo, Miaoli County, Taiwan, for $1.8 billion in cash. Concurrently, the two companies finalized a long-term partnership on DRAM wafer back-end packaging and assembly, helping PSMC enhance its niche DRAM product line.

　　In an interview following the groundbreaking ceremony for the New York fab, Manish Bhatia, Executive Vice President of Operations at Micron Technology, stated bluntly that the current memory chip shortage is indeed unprecedented. He noted that the shortage worsened over the past quarter and that supply tightness will persist beyond 2026, primarily driven by explosive demand for high-end semiconductors from AI infrastructure development. High-bandwidth memory (HBM), essential for manufacturing AI accelerators, is consuming significant industry capacity, directly causing supply shortages in traditional sectors like smartphones and PCs. According to reports, Micron has already sold out all its AI memory chips scheduled for delivery before 2026. The newly acquired fab is expected to significantly boost DRAM wafer output starting in the second half of 2027, serving as a critical supplement to alleviate capacity pressure.

　　Strong market demand has propelled Micron’s financial performance and market valuation sharply upward. Over the past three months, the company’s stock price has surged by 86%, with a one-year gain of 245%, rapidly pushing its market cap beyond $400 billion. For fiscal year 2025, revenue soared year-over-year to $37.38 billion, and adjusted earnings per share jumped to $8.29, highlighting the robust benefits of the industry’s upcycle.

　　Samsung and SK Hynix Accelerate Upgrades, Betting on HBF to Forge New Pathways
　　In response to AI-driven transformation in the memory market, South Korea’s two giants—Samsung and SK Hynix—are accelerating process upgrades and capacity expansion while focusing on new technologies to build competitive moats. Samsung has launched its Yongin National Industrial Complex project, planning a 360 trillion KRW investment to construct six wafer fabs covering both system semiconductor foundry and memory semiconductor production. Construction is slated to begin in the second half of 2026, with full completion targeted by 2031, forming a large-scale capacity matrix.

　　Meanwhile, SK Hynix has partnered with SanDisk to advance high-bandwidth flash (HBF) technology, jointly driving standardization efforts. The first HBF product, HBF1, is expected to adopt a 16-layer NAND flash stacking process, with samples anticipated in 2026. As a complementary successor to HBM, HBF offers significant advantages: storage capacity can reach 8–16 times that of current HBM, with a single stack supporting up to 512GB and eight stacks totaling 4TB. Its bandwidth matches HBM3, while cost per unit capacity is only 15%–20% of HBM’s, and power consumption is reduced by 20%–36%. This enables HBF and HBM to form an AI storage architecture combining “high-speed cache + high-capacity storage,” addressing data storage bottlenecks for trillion-parameter large models.

　　Professor Kim Jung-ho of KAIST, known as the “father of HBM,” revealed that Samsung and SanDisk plan to deploy HBF technology in actual products from NVIDIA, AMD, and Google between late 2027 and early 2028. Industry forecasts indicate the HBM market will reach $12 billion by 2030, with a compound annual growth rate exceeding 35% from 2024 to 2030, potentially surpassing HBM to become the dominant AI memory solution in the long term.

　　Price Hikes Persist Throughout the Year as Domestic Manufacturers Seize Expansion Window
　　The explosive growth in AI demand has pushed the global memory chip market into a “super cycle,” with price increases spreading across the board. TrendForce forecasts that general-purpose DRAM contract prices will rise 55%–60% quarter-over-quarter in Q1 2026, while NAND Flash contract prices will increase by 33%–38%, with server DRAM prices surging over 60%. Counterpoint Research notes that current market conditions have surpassed the 2018 historical peak, with suppliers’ pricing power at an all-time high. Prices are expected to rise another 40%–50% in Q1 2026, followed by an additional ~20% increase in Q2.

　　Supply-demand imbalance is the core driver of price hikes. On the demand side, AI servers require 8–10 times more memory than traditional servers, and NAND flash demand has increased by over 12 times, fueled by AI adoption among more than 15% of the global population, which drives soaring compute and model training needs. On the supply side, giants like Samsung and Micron have redirected 80% of their capacity toward high-margin advanced products like HBM and DDR5, reducing traditional memory output. Moreover, new capacity requires lengthy construction cycles, with the earliest additions not coming online until the second half of 2027—too late to close the 2026 gap. Currently, module makers hold only one month of DRAM inventory and 1.5 months of NAND inventory, while original equipment manufacturers and distributors maintain just 2–2.5 months of stock, further fueling price increases.

　　Institutions remain bullish on the AI memory supply chain. KCF Securities points out that price increases are evident across upstream semiconductor fabrication and packaging/testing segments. Ping An Securities believes domestic memory manufacturers face urgent expansion needs, creating investment opportunities in upstream semiconductor equipment. China’s memory industry is now entering a critical development window.
