TSMC has officially denied reports suggesting it is exploring 3D DRAM production at the request of Nvidia. The semiconductor giant clarified that it remains a pure-play logic foundry, rejecting claims that it is preparing to manufacture advanced memory chips to help solve the global shortage of AI hardware components.
The denial follows a recent report from The Information, which cited two sources familiar with the initiative. According to that report, TSMC had begun preparing plans for 3D DRAM manufacturing under the oversight of Hsu Kuo-chin, the company’s vice president for advanced packaging. The alleged initiative was driven by surging demand for AI accelerators, which has turned memory from a standard commodity into a critical strategic asset.
TSMC Reaffirms Logic Foundry Status
In a statement provided to Tom’s Hardware, a TSMC spokesperson emphasized the company’s commitment to its core business. “Please note that TSMC focuses on our core business at all times, which is dedicated IC foundry,” the spokesperson said. “Our mission is to be the trusted technology and capacity provider of the global logic IC industry for years to come.”
This statement serves as a direct contradiction to the narrative that TSMC is pivoting toward memory manufacturing. While TSMC is the world’s leading producer of logic chips, it does not currently possess the expertise or production capacity to make DRAM, let alone the more complex 3D DRAM structures. The company works closely with memory producers by packaging memory into system-in-packages for its customers, but this is distinct from fabricating the memory cells themselves.
Technical and Market Barriers to 3D DRAM
Even if TSMC were to pursue 3D DRAM, the technology is not a near-term solution for the current memory crunch. 3D DRAM places multiple levels of memory cells vertically to increase capacity per wafer, a process that requires entirely different fabrication techniques than conventional planar DRAM. All three leading memory makers, Micron, Samsung, and SK hynix, are actively working on their own 3D DRAM projects.
However, these companies are still years away from commercial viability. Micron, for instance, has indicated that it will roll out at least four more planar DRAM process technologies before 3D DRAM becomes a reality. Developing a competitive 3D DRAM manufacturing process without first having a leading-edge planar DRAM process is considered nearly impossible. TSMC lacks a competitive planar DRAM process, making the leap to 3D manufacturing a massive technical hurdle.
Entering the DRAM business would also expose TSMC to significant market risks. The memory industry is historically cyclical, with shortages often leading to overexpansion and subsequent price crashes. Furthermore, such a move could complicate TSMC’s relationships with its existing memory partners, particularly SK hynix, which recently partnered with TSMC to manufacture logic base dies for next-generation High Bandwidth Memory products.
Regulators might also scrutinize such a move for antitrust concerns. Combining TSMC’s dominant position in logic manufacturing and advanced packaging with memory production could raise questions about vertical integration and market fairness. While it could introduce competition into a market dominated by three manufacturers, the regulatory path would be complex.
Instead of manufacturing DRAM, TSMC is likely to continue expanding its role in the advanced memory ecosystem through other means. The company can capture value by producing sophisticated logic base dies for HBM, integrating memory with processors using its SoIC hybrid bonding technology, and developing customized memory solutions with established partners. This strategy allows TSMC to benefit from the AI memory boom without the billions in investment and technical risks associated with building a new DRAM fabrication division.
