Hot Chips 2026: Applying High Bandwidth Flash (HBF)

HBF, or High Bandwidth Flash, uses the same flash memory technology we see in SSDs today. Unlike SSDs, HBF is implemented much like HBM (High Bandwidth Memory). HBF cubes sit on the same package as a compute chip, perhaps even next to HBM. HBF’s idea is to offer much higher capacity than HBM, while still providing decent memory bandwidth. At Hot Chips 2026 tutorials day, Anurag Agarwal and Radhakrishna Giduthuri’s talk explores how HBF could apply to machine learning workloads. No HBF products e...
