Nvidia Pushes TSMC 3nm for Next-Gen AI Memory Chips
Nvidia’s 3nm memory play tightens supply chain grip—why this shifts costs and timelines for AI builders.
The story of the day
Nvidia is pressuring suppliers to adopt TSMC’s 3nm process for its next-gen high-bandwidth memory (HBM) chips, per Seoul Economic Daily. Samsung, SK Hynix, and Micron face a de facto standardization demand—aligning memory production with Nvidia’s GPU roadmap. For builders, this means tighter coupling between memory and compute, potential cost hikes as 3nm scales, and a supply chain increasingly dictated by a single vendor’s timeline. The move consolidates Nvidia’s control over the AI stack, from silicon to deployment.
