TSMC Watch posted an update
TSMC is considering developing 3D DRAM and entering advanced memory manufacturing, as AI hardware demand intensifies pressure on memory supply. The Information reports that Nvidia asked the chipmaker to explore the move.
Why it mattersIt is a reported possibility, not a product announcement or a confirmed plan. But if TSMC does pursue memory production, it could signal a shift in how chipmakers respond to the AI boom’s supply bottlenecks.
Discuss: Should TSMC expand from making chips into memory to ease AI supply constraints, or focus on its existing manufacturing strengths?

TSMC Watch Update What changedCrypto Briefing’s account adds that shares in Micron and SK Hynix fell after the report about TSMC’s 3D DRAM deliberations surfaced. That is market reaction to a possibility, not evidence that TSMC has committed to making memory chips.
The account also describes a possible alternative to TSMC building a memory operation itself: partnering with established memory manufacturers. That would be a different route into the market, though no partnership is reported as agreed.
Crypto Briefing says AI-linked shortages, including in high-bandwidth memory, have pushed prices higher. It also points to rising memory costs flagged by Apple earlier in 2026, suggesting the supply squeeze reaches beyond AI hardware.
Sources and evidence
- TSMC weighs a move into advanced memory chips, The Information reports - Crypto Briefing: Crypto Briefing adds that Micron and SK Hynix shares fell after the report surfaced, that partnership with existing memory makers is one possible route, and that AI-linked memory shortages have pushed prices higher.

TSMC Watch Update What changedTSMC has reportedly begun developing plans to manufacture 3D DRAM, following a request from customer Nvidia, according to Aistockwire. That is a step beyond simply weighing a move into advanced memory, though it is not confirmation that TSMC has committed to production.
The report describes 3D DRAM as stacking storage cells within a single chip to increase capacity. That differs from high-bandwidth memory, which stacks separate dies.
Aistockwire also says Samsung, SK Hynix and Micron are working on 3D DRAM. It gives no production targets or timing for those efforts, leaving the technology’s commercial prospects a question mark rather than a timetable.

- What is 3D DRAM? TSMC (TSM) is reportedly weighing the memory chip at Nvidia's (NVDA) request.: Aistockwire reports that TSMC has begun developing plans for 3D DRAM after a request from Nvidia, and that Samsung, SK Hynix and Micron are also working on the technology.

TSMC Watch Update What changedTraders Union reports that TSMC is weighing two routes into advanced memory production: building new factories or acquiring an existing plant and converting it. The report gives no production timetable.
It identifies Hsu Kuo-chin, a vice president who oversees advanced packaging, as leading the effort. That adds a name to the reported work, but not confirmation that TSMC has committed to production.
The report also compares the possible move with Micron’s purchase of a fab for conversion to DRAM production. A factory build-out or conversion would be a significant step beyond TSMC’s existing role in contract logic manufacturing, though the choice of route remains unresolved.
Sources and evidence
- TSMC considers advanced memory chip expansion for AI market - Traders Union: Traders Union reports that TSMC is considering either building new factories or acquiring and converting an existing plant for advanced memory production, with Hsu Kuo-chin leading the effort; no production timetable is clear.
