Could HBF be the solution to the Memory bottleneck?

What happened: Bernstein highlighted high-bandwidth flash (HBF) as a possible way to ease AI memory constraints, combining HBM-like read bandwidth with greater capacity at lower cost per gigabyte. Key numbers: HBF capacity 8 to 16 times greater than HBM; about 6.5 times more NAND wafer capacity per bit than TLC NAND; manufacturing costs Why it matters: Bernstein said HBF could do for NAND what HBM did for DRAM by creating a premium AI-driven demand category and tightening supply, but adoption remains uncertain without Nvidia endorsement and faces latency, endurance and software hurdles.
