SanDisk and SK hynix unveil HBF spec via OCP, enabling GPUs to add up to 512GB storage with 3 TB/s bandwidth using 16-Hi NAND stacks and UCIe for AI inference

SanDisk and SK hynix unveil HBF spec via OCP, enabling GPUs to add up to 512GB storage with 3 TB/s bandwidth using 16-Hi NAND stacks and UCIe for AI inference—adoption uncertain

New HBF spec outlines tech that can give GPUs terabytes of extra memory — Sandisk and SK hynix unveil spec with up to 16-Hi NAND stacks, 3 TB/s bandwidth, UCIe

(Image credit: SanDisk) Sandisk and SK hynix on Tuesday formally introduced the High Bandwidth Flash (HBF) specification, their jointly developed storage technology that promises to bring together the non-volatility of 3D NAND and the performance of High Bandwidth Memory (HBM), which will be handy for AI inference systems. The specification was released through the Open Compute Project (OCP), so it will be an open standard rather than a proprietary interface.Tom's Hardware Premium RoadmapsThe in...
