SK Hynix says the future of memory lies somewhere between HBM and SSDs - Notebookcheck

SK Hynix has introduced a new memory standard called High Bandwidth Flash (HBF), positioned between traditional High Bandwidth Memory (HBM) and NAND flash used in conventional SSDs. Designed to combin... Read original →

SK Hynix's introduction of High Bandwidth Flash (HBF) marks a pivotal shift in memory architecture, merging HBM’s high bandwidth with NAND’s capacity, using UCIe for cross-platform compatibility. This addresses current bottlenecks in data center and AI accelerator memory hierarchies, prompting upstream chip design and packaging advancements, while reshaping downstream SSD and HBM supplier dynamics. From a compliance standpoint, the open standard mitigates geopolitical risks, though commercial adoption remains years away. Competitors like Micron and Infineon may accelerate similar initiatives to capture future Tiered Memory market share. Initially targeting enterprise systems, HBF’s eventual consumer impact could be transformative, especially amid rising compute demands, potentially triggering a new wave of storage architecture evolution.
