SK hynix and SanDisk announce new High Bandwidth Flash — speedy HBF standard is targeted at inference AI servers

SK hynix and SanDisk have introduced a new High Bandwidth Flash (HBF) standard aimed at inference AI servers. The HBF is designed to bridge the gap between HBM DRAM and flash SSDs, potentially offering speeds of at least 10 GB/s per chip. Power efficiency is a key focus, considering the energy demands of data centers. While specific implementation details are scarce, HBF could function as a large cache or a high-speed block storage device. The companies anticipate a rise in demand for complex memory solutions like HBF around 2030, with the standard overseen by the Open Compute Project.
