Industry Analysis
The AI compute arms race is elevating high-bandwidth memory (HBM) to the apex of the semiconductor value chain. Micron’s deal with Anthropic not only locks in advanced packaging capacity but also compels TSMC to prioritize HBM3E allocation on its CoWoS lines, indirectly squeezing GPU makers’ wafer quotas. This technical cascade accelerates commercial adoption of near-memory computing, pressuring Samsung and SK Hynix to ramp TSV stacking yields. Geopolitically, U.S. export controls now cover HBM modules, inflating compliance costs for foundries in Taiwan, China by over 15%. Facing Micron’s near-85% gross margins, Samsung may abandon price wars and pivot toward co-developing HBM-PIM chips with Microsoft Azure. Over the next 18 months, memory will exceed 40% of AI server BOM costs, enabling second-tier players like CXMT to penetrate edge AI via LPDDR5X—establishing a dual-track market: premium HBM for data centers, mid-tier LPDDR for inference.
