TSMC Weighs 3D DRAM Production for Nvidia
Taiwan Semiconductor Manufacturing Co. is reportedly drawing up plans to build advanced memory chips at Nvidia's request.
Updated on Nov. 6, 2026 in Semiconductors
TSMC stock climbed more than 6% in early trading Friday after reports that the chipmaker is considering manufacturing 3D DRAM chips at the request of Nvidia, its biggest customer. The company is weighing new memory factories or the acquisition of an existing semiconductor facility for conversion.
Why it matters
Demand for AI hardware is pressuring memory chip supplies, and a move by TSMC into DRAM would widen its role beyond logic chip manufacturing. The reported plans signal how closely leading chipmakers are coordinating with major customers to secure capacity for AI workloads.
3D DRAM uses vertically stacked memory cells rather than a single horizontal layer, and TSMC holds patents related to vertical DRAM technology. Whether TSMC will build new capacity or convert an existing facility remains unconfirmed.
The players
Taiwan Semiconductor Manufacturing Co. (TSMC)
TSMC is the world's largest contract chipmaker, producing logic chips for major technology companies and holding a central position in the global semiconductor supply chain.
Nvidia
Nvidia is a leading designer of graphics processors and AI accelerators and is TSMC's largest customer.
Micron Technology
Micron is a U.S. memory chipmaker and a major producer of DRAM and NAND flash products.
The details
Reports say a TSMC vice president responsible for advanced packaging operations, Hsu Kuo-chin, is leading the effort to draw up plans for 3D DRAM manufacturing. The proposal is linked to a request from Nvidia, and TSMC previously signed a memorandum of understanding with SK Hynix in April 2024 to collaborate on HBM4 development.
Timeline
April 2024: TSMC and SK Hynix signed a memorandum of understanding on HBM4 collaboration.
March: Micron agreed to acquire a Taiwan-based facility from Powerchip Semiconductor Manufacturing for $1.8 billion.
Friday: TSMC stock rose more than 6% in early trading on the report.
The Tech Race
The reported plan extends the vertical stacking approach already used in High Bandwidth Memory for AI accelerators into a new DRAM architecture. It also places TSMC in direct competition with memory makers such as Micron and SK Hynix for AI-driven memory capacity.
Memory supply tightness driven by AI hardware demand can affect the availability and pricing of devices that rely on DRAM. Any move by TSMC into memory production would not reach consumer products until years after development begins.
The takeaway
Chipmakers are increasingly coordinating with their largest customers to secure memory capacity for AI workloads. Readers should expect that moving from development to large-scale production of new memory architectures could take years.
