  "summary": "Sandisk and SK Hynix have announced the High Bandwidth Flash (HBF) open specification, which enables memory modules with capacities of up to 512GB and bandwidth ranging from 0.4 TB/s to 3.0 TB/s. The specification was released through the Open Compute Project.\n\nThe HBF specification supports capacities of up to 512GB using 8-high and 16-high NAND stacks. According to Slashdot, it also uses the UCIe chiplet interface, which could make HBF easier to integrate with CPUs, GPUs, and other accelerators.\n\nGoogle and Tenstorrent participated in the standardization effort. However, commercial products and independent benchmarks are still missing.",
