The hyperscaler memory tax quarter. More CapEx? Pssh. We knew flops needed scaling. But $25B at Microsoft alone just to pay higher component prices?  A memory tax. That's the news. NAND? Sold out. HBM? Sold out. What we cover: * SanDisk revenue +97% sequential. * 78% gross margin. Guidance above 80% next quarter. * Samsung HBM4 first to ship. Demand outstripping supply. * DeepSeek v4 goes SSD-centric. KV cache offloads to flash. * Microsoft: $25B of 2026 CapEx is just memory pricing. * Jassy: memory shortage pushes on-prem to AWS. * Qualcomm: mystery custom ASIC. Ships December. New Semi Doped with @vikramskr and @austinsemis.
