On August 4, 2026, at FMS 2026 (Future Memory and Storage), held in Santa Clara, California, USA, SK hynix and SanDisk officially released the first OCP technical specification for High Bandwidth Flash (HBF).
Server memory is high-speed dynamic random-access memory specifically designed for servers and data center equipment. It serves as a data exchange buffer between the CPU and persistent storage such as hard drives and solid-state drives.
SLC cache stands for Single-Level Cell Cache and is also commonly called pseudo-SLC cache or simulated SLC cache. It is not an independent hardware cache chip on the SSD circuit board. Instead, it is a software optimization implemented by the controller firmware.
SSDs do experience performance changes with use, but most of the slowdown people notice in daily use is not caused by hardware aging. Most performance loss comes from reversible factors such as insufficient disk space, exhausted SLC cache, or improper system settings.
On August 4, 2026, Samsung Electronics formally unveiled the industry’s first zHBM concept model, alongside a vertical stacking solution for NAND flash named zNAND‑O. Designed for next‑generation ultra‑scale AI computing, zHBM represents a groundbreaking memory architecture
