Micron and Western Digital’s (including SanDisk) stock surges reflect real demand from AI infrastructure, not speculative froth. Technologically, HBM3e and DDR5 adoption is accelerating DRAM scaling to 1β/1γ nodes, while NAND exceeding 300 layers faces yield bottlenecks in CMOS-memory monolithic integration. On compliance, U.S. export controls are forcing Micron to shift capacity to India and Japan—but extended equipment lead times inflate CapEx, and any disruption to logistics hubs in Taiwan, China or Hong Kong, China risks SSD module delays. Competitively, Samsung is cutting DRAM investments to support pricing, while SK Hynix is locking in HBM supply with NVIDIA’s GB200 ecosystem, forming an 'AI memory alliance.' Over the next 12–24 months, even if consumer electronics remain weak, AI data centers will sustain a structural shortage in high-end memory, ushering in a 'high-price, high-volume' cycle—breaking the industry’s historical boom-bust pattern.
