TSMC is reportedly considering a move into 3D DRAM, a type of memory that stacks cells vertically rather than arranging them in a single layer. The proposal is said to follow a request from Nvidia, TSMC’s largest customer, but the available reporting describes plans under consideration—not a confirmed production launch. 11

What TSMC is reportedly considering
Reuters relayed The Information’s report that TSMC had started charting plans for 3D DRAM, citing two people with direct knowledge of the matter. The potential move would broaden TSMC’s role in AI hardware: instead of focusing on making chips for customers, it could also enter advanced memory manufacturing. 17

In conventional DRAM, memory cells are arranged in a single layer; the reported 3D approach stacks them vertically to fit more memory. The reports do not establish how TSMC would implement the design or what capacity it could produce. 11

Why memory supply is part of the story
Investing.com linked the proposal to tight memory availability and higher hardware costs. Its report said Nvidia and Apple were seeking alternative sources of memory, and that Apple had raised prices across its hardware portfolio earlier in the year after absorbing higher memory costs. Those are reported market pressures, not confirmation that TSMC’s plans will resolve the shortage. 40
If TSMC proceeds, it would compete in advanced memory with established suppliers Samsung, SK Hynix and Micron. The Information’s post described both building new facilities and acquiring an existing plant for conversion as options under consideration; it compared the latter with Micron’s reported $1.8 billion plant purchase in March. The available material does not establish a finalized site or investment plan. 16

What the stock reaction does—and does not—show
The Economic Times reported that TSMC stock rose more than 6% in early trading on Friday, November 6, 2026. Investing.com reported a 7.7% early-trading gain for TSMC’s U.S.-listed depositary receipts. These are early-session figures reported by different outlets, not a closing return or evidence that production has been approved. 2

What remains unconfirmed
The reports do not establish a production start date, planned capacity, factory location or final investment decision. Reuters also said TSMC and Nvidia had not immediately responded to its requests for comment. Until the companies confirm more, the clearest conclusion is that TSMC is reportedly exploring a possible expansion into AI memory at Nvidia’s request—not that it has committed to making 3D DRAM. 1
