Industry Analysis
The surge in agentic AI applications is redrawing memory technology roadmaps. Micron’s HBM3E dominance in data center DRAM has secured 2026 capacity commitments from NVIDIA and Microsoft, while Western Digital’s (SanDisk’s parent) upcoming High-Bandwidth Flash (HBF) targets a critical gap in low-latency, high-throughput non-volatile storage for AI inference—directly threatening Samsung and SK hynix’s NAND moats. Geopolitically, U.S. CHIPS Act subsidies ease capex burdens, but rapid HBM ramp-ups in Taiwan, China and mainland China risk triggering stricter export controls, inflating compliance overhead. Samsung may counter by accelerating GAA-based NAND deployment. Crucially, as AI clusters shift toward memory-centric architectures over the next 18 months, DRAM/NAND vendors will evolve from component suppliers to system architects—elevating Arm and Dell’s strategic leverage far beyond current market recognition.
