Samsung Outsources Nvidia AI Memory Base Dies to TSMC as Foundry Yields Fall Short

Samsung will source base dies for Nvidia's NVHBM memory architecture from TSMC's 3nm process due to yield rate gaps in its own SF2 process. All major HBM vendors (Samsung, SK Hynix, Micron) will use TSMC for NVHBM base dies, making TSMC the sole logic foundry for premium AI memory. The shift is driven by NVHBM's architectural changes, which require advanced logic manufacturing.

Nvidia reportedly wants all its HBM suppliers to use TSMC’s 3nm process

Nvidia requires suppliers (Samsung, SK Hynix, Micron) to use TSMC’s 3nm process for NVHBM base dies, aiming for consistency. Samsung agreed, marking their first collaboration on HBM. NVHBM offers 30% more bandwidth, 15% less power than standard HBM4E. UBS forecasts a 10% HBM supply gap in 2024. TSMC plans 3nm production expansion. Samsung maintains turnkey approach for other HBM products.
