Can Nvidia Secure a Greater Share of the AI Supply Chain by Steering TSMC towards Advanced Memory Chips and Exploring 3D DRAM Production?

The artificial intelligence hardware supply chain could see TSMC extend its influence further if its plans for advanced memory chip production take shape. At the request of Nvidia, its largest customer, the world’s largest contract chipmaker has begun preparing plans to manufacture 3D DRAM as it considers a move into advanced memory manufacturing. TSMC has recently begun assessing production options for 3D DRAM.

Nvidia’s requirement for advanced memory chip supplies is behind the initiative, highlighting efforts by AI chip designers to diversify their sources of essential components. Built around a three-dimensional structure, 3D DRAM is an advanced memory technology intended to raise memory density through new memory cell layouts and manufacturing processes. This would provide future high-performance computing systems with a wider range of technological options. A move into advanced DRAM manufacturing would broaden TSMC’s business beyond its longstanding focus on logic chip production and advanced packaging.

A move into advanced memory production could extend TSMC’s role across more of the critical components used in AI computing hardware. The company already dominates global advanced logic chip manufacturing and serves as a key manufacturing partner for Nvidia’s AI accelerators.

Severe supply constraints in the global memory chip market form the backdrop to this possible expansion. As generative AI and data centre construction continue to boom, demand for high-performance computing hardware and the memory chips that support it is growing rapidly. The resulting pressure on supplies is driving prices sharply higher.

Memory shortages could increase hardware production costs and constrain the rollout of AI infrastructure. For AI chip designers such as Nvidia, these chips are essential to both computing system performance and production scale. To mitigate supply chain risks, major technology companies, including Nvidia and Apple, are actively looking for additional memory chip suppliers.

In these conditions, encouraging TSMC to assess 3D DRAM production could help Nvidia establish a more diversified network of advanced memory chip suppliers in the future.

Market Insight: What Would 3D DRAM Mean for TSMC?

Still at the preliminary research and planning stage, the proposals do not yet include any disclosed details from TSMC on potential investment, prospective production capacity or a mass-production timetable. Nor has the company disclosed whether it will formally move ahead with commercial production. The technological path for 3D DRAM also differs from that of the high-bandwidth memory widely used in current AI accelerators. Exploring 3D DRAM production therefore does not indicate that TSMC has decided to enter the existing HBM market.
