SanDisk Reports Exploding AI NAND Demand with Long-Term Contracts Extending to 2030
SanDisk announced during its fiscal Q1 2027 earnings call that surging AI inference demand is driving massive long-term NAND contracts stretching to 2030 and beyond, alongside the tape-out of its new High Bandwidth Flash (HBF) technology. This trend signals that AI inference is fundamentally reshaping the semiconductor memory market by creating unprecedented demand for high-capacity storage tiers, prompting companies to rethink memory hierarchies and lock in multi-year supply agreements. SanDisk's New Business Model (NBM) protocol has already locked in about 50% of fiscal 2027 bit shipments, while its newly taped-out HBF storage die aims to provide HBM-like reading bandwidth with large NAND-like capacity to support extended context windows and KV caches.
## BACKGROUND
High Bandwidth Flash (HBF) is an emerging technology designed to bridge the gap between slow, high-capacity SSDs and fast, low-capacity High Bandwidth Memory (HBM). By integrating flash more closely with GPUs through stacked configurations, it provides a specialized memory tier for massive datasets and inference workloads.
