Industry Analysis
The AI infrastructure boom is triggering a cascading reshaping of the memory stack: surging demand for HBM3E/HBM4 not only fuels Micron’s 81% gross margin but also forces rapid scaling of advanced packaging, TSV, and CoWoS capacity—benefiting ASE and Samsung. Meanwhile, tightening U.S. export controls elevate compliance costs and customer concentration risks across supply chains in Taiwan, China and South Korea, especially as NVIDIA’s custom HBM orders dominate revenue. In response, SK Hynix will accelerate HBM4 ramp-up, while Samsung may pivot to GDDR7; Seagate faces looming price pressure from Western Digital in enterprise QLC SSDs. Over the next 12–24 months, as AI workloads shift from centralized training to distributed inference, new heterogeneous memory standards combining CXL and HBM will emerge—granting pricing power to those mastering this convergence.
