If High Bandwidth Flash or HBF proves to be a commercial success, it would likely preclude cheaper SSDs for the foreseeable future, especially as HBF presumably entails just one-tenth of the cost of a comparable HBM4 stack, leading to a Jevons paradox-driven incremental demand. An 8-Hi stack of HBF will cost $0.64 per GB vs. the $6.78 per GB cost for an 8-Hi HBM4 stack For the benefit of those who might not be aware, just as HBM stacks DRAM, HBF stacks NAND die on top of each other, with Through Silicon Vias (TSVs) connecting the dies together and a […]
