Micron’s HBM Surge Could Redefine the AI Growth Story - The Globe and Mail

Micron's strong financial performance in its latest fiscal quarter underscores the critical role of high-bandwidth memory (HBM) in driving the AI revolution. As global tech leaders race to implement A... Read original →

Micron’s HBM surge isn’t just demand-driven—it’s reshaping the co-design paradigm between memory and logic. Upstream, EUV and 3nm advanced packaging bottlenecks intensify; downstream, GPU architectures like NVIDIA’s Blackwell are now bandwidth-constrained, mandating 12-Hi stacks. Geopolitically, while U.S. CHIPS Act subsidies ease CapEx, reliance on advanced packaging hubs in Taiwan, China and South Korea remains acute—any export control escalation would inflate delivery costs across the board. Against SK Hynix and Samsung’s HBM3E lead, Micron is countering with TSV yield breakthroughs. Intel’s potential Gaudi3 scale-up could shift buyer leverage. Within 18 months, HBM will evolve from optional to mandatory for AI silicon performance, and even post-2028 capacity ramps won’t eliminate high-end shortages. With long-term cloud contracts locked in, Micron’s valuation is pivoting from cyclical to growth-oriented.
