SNDK•SK hynix and Sandisk publish first HBF standard specification
SK hynix partnered with Sandisk to publish the first High Bandwidth Flash (HBF) standard specification via the Open Compute Project.
- HBF targets a new tier between HBM and SSDs, aiming to ease AI infrastructure bandwidth constraints while scaling capacity.
- The spec covers up to 512GB in 8-high or 16-high NAND stacks, with bandwidth grades spanning about 0.4 TB/s to 3.0 TB/s.
- Google and Tenstorrent joined the HBF consortium as SK hynix seeks broader adoption through an open, multi-company ecosystem.
