SK Hynix and Sandisk move to standardize HBF, shaking up AI memory ecosystem

What happened

SK Hynix and Sandisk formed a consortium to standardize High Bandwidth Flash (HBF) technology, positioning it as a next-generation memory layer for AI inference. This move signals intensified competition in the advanced memory space, particularly as Micron also ramps its HBM4 and NAND efforts. Neutral: This is a long-term R&D and ecosystem-building initiative with no immediate impact on supply, demand, or pricing of current components.
