High Bandwidth Flash: Bridging the Gap Between Expensive HBM & Flash Memory

At the recent FMS 2026, SK hynix and SanDisk announced the first open technical specification for High Bandwidth Flash (HBF), formalizing a new memory category that sits between high-bandwidth memory (HBM) and solid-state drives.
FMS 2026: AI Moving Boundaries Between Memory & Storage

The recent FMS 2026 conference in Santa Clara, once organized around flash storage, now functions as an AI memory-and-data-infrastructure conference, confirming a shift that has been building over several product cycles. It’s no wonder the event changed its name from “Flash Memory Summit” to “Future of Memory and Storage.”
