Sandisk and SK hynix join forces to standardize High Bandwidth Flash memory, a NAND-based alternative to HBM for AI GPUs — Move could enable 8-16x higher capacity compared to DRAM

Sandisk and SK hynix have announced they're collaborating on High Bandwidth Flash (HBF)-a potential alternative to traditional, DRAM-based HBM for AI GPUs. Instead of only relying on DRAM, HBF adds NAND to the memory stack, allowing for non-volatility that can cut energy (and thermal) costs, along with upping the storage capacity.
