Can QLC Flash Memory Challenge HBM? SanDisk and Kioxia Unveil 9th-Gen QLC — and an AI Memory Repricing
One-sentence takeaway: AI memory demand is spreading from HBM to NAND flash. SanDisk and Kioxia's 9th-generation 2Tb QLC, paired with the new HBF architecture, could rewrite NAND's role in AI — and repric the entire AI hardware supply chain. One announcement, a 5.73% single-day surge On August 13, SanDisk shares jumped 5.73% in a single day, ignited by the company's joint unveiling with Kioxia of 9th-generation 2Tb QLC 3D flash memory built for AI infrastructure. This is no routine product refresh — industry analysts point to a repricing of the AI memory market worth up to $94 billion , and QLC, once dismissed as the "slow, cheap" storage technology, is now at the center of it. Why QLC was dismissed — and why it's back QLC stores 4 bits per cell (TLC stores 3), delivering higher density and lower unit cost at the expense of speed and endurance. That made it a natural fit for consumer SSDs and cold storage — but the AI era has changed the game. Larg...
