Micron detailed NVHBM, its custom HBM package for NVIDIA: moving the memory controller from the compute die into the base die cuts power by 15%, boosts memory bandwidth by up to 30%, and shrinks I/O PHY package area by up to 67% via an integrated custom PHY.
NVIDIA says NVHBM beats standard HBM4E with up to 30% greater bandwidth and 15% lower HBM power consumption. The poster is impressed — but expects the price to match.
