TSMC weighs 3D DRAM production after Nvidia asks for more memory supply

The Information, via reachable press, says TSMC has begun planning vertically stacked 3D DRAM at its largest customer’s request; no timeline or fab plan is confirmed, and TSMC has not commented.
Why it matters
Memory has become a binding constraint on AI hardware alongside leading-edge logic. If TSMC, historically a pure-play logic foundry, enters 3D DRAM, it would compete with Samsung, SK hynix and Micron in a cyclical business while answering Nvidia’s request for more supply. The reporting stresses plans, not commitments: no production date, capital figure or site is public. Watch for any TSMC confirmation, a partnership with an incumbent memory maker, or Nvidia commentary on memory sourcing.
Key facts
- The Information cites two people: TSMC planning 3D DRAM at Nvidia’s request
- No production timeline, investment figure or fab site disclosed
- Samsung, SK hynix and Micron currently lead advanced DRAM
- Finimize and TechFlow republished the report on 6 Nov 2026
- TSMC has not publicly commented
