TSMC reportedly weighs 3D DRAM production at Nvidia’s request
TSMC has reportedly begun internal planning to manufacture advanced 3D DRAM memory chips at the request of Nvidia, marking a notable shift for the chipmaker that has historically stayed out of the memory business.
The reported planning phase indicates this is a long-term strategic bet rather than a quick solution to the current memory constraints. TSMC's third-quarter 2026 revenue reached $46.72 billion with a gross margin of 66.4%, with high-performance computing accounting for 68% of sales, largely driven by AI applications.
Exploring Production Options
The project, led by TSMC's Hsu Kuo-chin, is reportedly evaluating multiple approaches including building new fabrication facilities or adapting existing ones. No firm decisions have been made regarding capital commitments or production timelines.
Memory Shortage Driver
Nvidia's request stems from a severe memory shortage driven by AI demand that is expected to impact supply and pricing through 2028. Memory suppliers like Micron have already voiced concerns about continued supply constraints as AI data centers absorb increasing capacity.
Relying on a narrow group of memory makers during a prolonged shortage is a risk no major chip designer wants to carry.
Industry Implications
TSMC's potential entry into 3D DRAM production could challenge specialized memory makers like Micron in the market. For Nvidia, securing an additional memory source reduces dependence on constrained suppliers during peak demand periods.
The work being placed under TSMC's advanced packaging group reflects how the boundary between processors and memory is increasingly blurring in modern chip design.
