New HBF spec outlines tech that can give GPUs terabytes of extra memory — Sandisk and SK hynix unveil spec with up to 16-Hi NAND stacks, 3 TB/s bandwidth, UCIe
PC Components Storage SSDs Sandisk and SK hynix unveil HBF spec — up to 16-Hi NAND stacks, 3 TB/s bandwidth, UCIe News By Anton Shilov Published 4 August 2026 The specification is here, but what about the interest?

In fact, Sandisk once called them HBF core dies rather than 3D NAND die stacks.Performance of HBF is divided into three bandwidth grades ranging from approximately 0.4 TB/s to 3.0 TB/s (though we are not sure whether this figure describes the full HBF subsystem or per-package bandwidth).
