TSMC’s reported 3D DRAM push is an unconfirmed proposal, not an announced manufacturing program. The Information, citing two people familiar with the plans, said TSMC had begun drawing up plans at Nvidia’s request. TSMC later reiterated its focus on dedicated logic-chip foundry work, leaving the report’s central premise in dispute.1

What was reported—and how firmly it is sourced
Reuters and Bloomberg both relayed The Information’s account, which cited two people familiar with the initiative. Their reports describe the same underlying story; the available excerpts do not provide separate, independent confirmation of TSMC’s plans.1
2
The reported rationale is that AI demand is putting pressure on memory supply and that Nvidia, TSMC’s largest customer, wants more advanced memory. The proposed move could broaden TSMC’s role in the AI hardware supply chain, but reporting about a possible plan is not evidence that the company has approved or started a DRAM manufacturing program.1

TSMC’s U.S.-listed shares reportedly rose 6.26% on November 6, 2026, following the report. That market move reflects investor reaction to the news; it does not confirm the reported initiative.
How the reported 3D DRAM differs
Conventional DRAM cells are arranged in a planar, or horizontal, structure. The reported 3D DRAM concept instead stacks memory cells vertically to increase capacity. The available reports do not specify the proposed design or manufacturing process, and do not clearly establish whether “3D DRAM” refers to vertically structured cells or to a different form of stacking.
TSMC has also been associated with patent work on vertical DRAM architectures involving vertical transistors and integrated capacitors. Patents indicate technical exploration; by themselves, they do not show that a commercially viable product or production plan exists.
The source material available here does not verify a history of TSMC manufacturing DRAM. It therefore cannot support a claim that the reported proposal would extend an established memory-production business.
Possible facilities and project leadership
Reports described two possible facility routes: build new factories, or acquire an existing plant and convert it for memory production.5
6 The Information’s social post also cited Micron’s reported $1.8 billion purchase of a facility as a precedent for the acquisition-and-conversion option. These are reported possibilities, not a confirmed TSMC site decision or investment commitment.
Secondary accounts identify Hsu Kuo-chin, a TSMC vice president responsible for advanced packaging, as leading the reported evaluation; one account also says he previously worked at Micron.6
7 Those details remain part of the unconfirmed reporting, not an announcement from TSMC.
Why the report remains uncertain
TSMC’s response cuts against the idea that it is pursuing the reported move. Tom’s Hardware reported that the company denied exploring 3D DRAM and quoted its spokesperson reaffirming TSMC’s focus on dedicated integrated-circuit foundry work and logic chips.18 That establishes the company’s stated position, though it does not independently resolve what discussions may or may not have taken place internally.
The available coverage also offers no confirmed production schedule, facility, capacity, or investment plan. Tom’s Hardware characterized advanced 3D memory as years from market viability, which underscores why the report should not be read as a near-term fix for current memory constraints.18
If TSMC eventually entered commercial DRAM production, it would move beyond its reported logic-foundry focus and into a market associated with Samsung, SK hynix, and Micron.3
7 But that remains a possible strategic implication—not a confirmed competitive move. The supplied evidence also does not establish claims about Apple seeking alternative suppliers or the specific effects of memory costs on hardware prices.
What to take away
The strongest supported conclusion is narrow: The Information reported preliminary TSMC planning at Nvidia’s request, and its account cited two people familiar with the plans. TSMC subsequently stated that it remains focused on dedicated logic-chip foundry work. Until there is clearer confirmation, the report should be treated as disputed—not as proof of a coming TSMC DRAM business or new memory supply.1
