## Summary

TSMC has reportedly begun drafting plans to manufacture 3D DRAM chips at Nvidia's request, according to The Information. No production timeline has been set, and TSMC says its focus remains on its core logic foundry business. The author says a TSMC entry would give Nvidia a fourth advanced memory supplier beyond Samsung, SK Hynix and Micron.

Nvidia is trying to create a 4th source of advanced memory.

They have reportedly asked TSMC to become a 4th supplier of advanced memory.

And TSMC reportedly has started drafting plans to make 3D DRAM chips at Nvidia’s request. 

means right now Nvidia can buy advanced memory from only 3 companies: Samsung, SK Hynix and Micron. 

If TSMC starts making it too, Nvidia gets a 4th place to buy from, which means more supply and less power for the other 3 to raise prices.

The request builds on Nvidia’s reported October requirement that the 3 memory makers all use TSMC’s 3nm process for its custom HBM base dies, so Nvidia can shift order volume between them during shortages. 

3D DRAM gives TSMC an opening because no incumbent has turned it into a mature product yet, and TSMC already holds its own vertical DRAM patents.
