Summary

The memory industry is experiencing significant flux at the close of 2025, driven by insatiable demand for high-bandwidth memory (HBM) in AI data centers. Micron CEO Sanjay Mehrotra projects tight memory markets beyond 2026, with Micron and SK hynix already selling out HBM inventory for 2026. Micron is reportedly evaluating a potential acquisition or strategic alliance with Taiwan-based Powerchip Semiconductor Manufacturing Corp. (PSMC) for its 12-inch Tongluo fab, which specializes in memory manufacturing and includes silicon interposer and 3D IC technologies. Concurrently, China's ChangXin Memory Technologies (CXMT), the fourth-largest global DRAM maker, plans a $4.2 billion IPO in Shanghai to expand wafer capacity and invest in next-generation DRAM and HBM, aiming to capitalize on current shortages and its 4% global DRAM market share in Q2 2025. These developments, alongside a technology espionage case involving Samsung engineers and CXMT, signal a pivotal and active year ahead for the DRAM industry.

Key takeaway

For CTOs and VPs of Engineering managing AI infrastructure, the severe HBM shortages and projected market tightness through 2026 necessitate immediate strategic action. You should prioritize securing long-term memory supply agreements and explore alternative memory architectures or suppliers to mitigate supply chain risks and ensure sustained AI workload performance. Consider diversifying your memory procurement strategy beyond the traditional top-tier vendors.
