3D DRAM Production: Nvidia Explores a Route to a Greater Share of the AI Supply Chain While Pushing TSMC into Advanced Memory Chips!

3D DRAM production is under assessment at TSMC. At Nvidia’s request, the world’s largest contract chipmaker has started preparing production plans while considering an expansion into advanced memory chip manufacturing. Nvidia is its largest customer. Realising these plans could increase TSMC’s influence across the artificial intelligence hardware supply chain. Its examination of production options for 3D DRAM began recently.

Behind the initiative is demand from Nvidia for advanced memory chip supplies, alongside efforts among AI chip designers to widen their sourcing of critical components. As an advanced memory technology, 3D DRAM employs a three-dimensional structure. New memory cell layouts and manufacturing processes are intended to increase memory density, broadening the technology options for future high-performance computing systems. Advanced DRAM manufacturing would add another business area for TSMC, whose established focus has been logic chip manufacturing and advanced packaging.

A dominant manufacturer of advanced logic chips globally, TSMC also acts as a key production partner for Nvidia’s AI accelerators. Producing advanced memory chips could extend its participation to additional critical parts of AI computing hardware.

Global memory chip supplies are severely constrained as TSMC considers this expansion. Sustained growth in generative AI and data centre construction is rapidly lifting demand for high-performance computing hardware and its supporting memory chips. Supply is tightening as a result, driving prices sharply upwards.

Memory chips help determine both computing system performance and production scale for Nvidia and other AI chip designers. Insufficient supply could push up hardware manufacturing costs and restrict the pace of AI infrastructure deployment. Reducing supply chain risk has therefore become a reason for major technology companies, including Nvidia and Apple, to actively seek additional memory chip suppliers.

With these pressures in view, Nvidia could develop a broader advanced memory chip supply network in future by encouraging TSMC to examine 3D DRAM production.

Market Insight: 3D DRAM Still Under Study

Only preliminary research and planning are under way. No details have been disclosed by TSMC on the potential investment scale, prospective production capacity or mass-production schedule. It has also not disclosed whether commercial production will formally proceed. Separately, the technology route for 3D DRAM differs from that of the high-bandwidth memory widely deployed in current AI accelerators. Assessing 3D DRAM production should therefore not be read as a decision by TSMC to enter the existing HBM market.
