TSMC Reportedly Considering 3D DRAM Production at Nvidia's Request, Expanding into Memory Chips
nashnova research
TSMC is reportedly studying 3D DRAM manufacturing, pushed by its largest customer Nvidia; if the plan materialises, the foundry giant would step directly into the memory market dominated by Samsung, SK Hynix and Micron — reshaping the AI hardware supply chain.
What is 3D DRAM, and why does TSMC want in?
3D DRAM — memory cells stacked vertically layer by layer — packs more capacity into the same chip area than conventional single-layer DRAM.
Surging AI hardware demand has left memory chips in tight supply with sharply rising prices; Nvidia, Apple and other chip designers are hunting for alternative sources — Apple has already raised prices on some products, citing higher memory costs.
This means → Nvidia's core motive in pushing TSMC to enter is breaking the three-player oligopoly of Samsung, SK Hynix and Micron, securing an additional supply line.
Who is leading the effort, and where will capacity come from?
The project is led by Hsu Kuo-chin, TSMC's VP in charge of advanced packaging; he previously ran Micron's Taiwan operations, giving him experience in both memory manufacturing and chip integration.
TSMC is exploring two capacity paths: build a new fab, or acquire an existing facility and convert it to a memory line — the latter mirrors Micron's March deal to buy a Powerchip factory for $1.8 billion.
In plain terms = TSMC hasn't decided how to build capacity yet, but it is seriously comparing "start from scratch" against "buy and retrofit."
Will this clash with the SK Hynix partnership?
In 2024 TSMC struck a deal with SK Hynix to manufacture the base die for Hynix's next-generation high-bandwidth memory (HBM).
If TSMC makes its own memory, the relationship flips from "foundry partner" to "direct competitor" — a clear conflict of interest.
This reflects a deeper strategic tension: the further TSMC extends up the value chain in the AI era, the blurrier its boundaries with existing clients and partners become.
What does TSMC say?
TSMC denied the report, stating it "remains focused on its core business of dedicated IC foundry" and that its mission is to be "the long-term trusted technology and capacity provider of the global logic IC industry."
Nvidia did not respond to a request for comment.
This means → the official line still locks to a "pure foundry" identity, yet the sourcing, the executive leading the effort and the capacity-path research all point to a plan already in active development.
What is the biggest uncertainty?
Manufacturing is extremely hard: as 3D DRAM stacking layers increase, complexity and defect risk rise in tandem; Samsung, SK Hynix and Micron have decades of accumulated expertise on this front.
The memory industry is deeply cyclical with volatile pricing — if supply-demand dynamics reverse, TSMC may slow or shelve the plan.
In plain terms = TSMC has the technical foundation and patent portfolio, but whether it can convert lab-level capability into reliable, high-volume production is the make-or-break variable for the entire effort.
