NAND flash memory
NAND flash technology keeps advancing, and supply and pricing are a separate question. Samsung introduced bonding-based V10 NAND in August and presented other architectures as concepts. That does not prove supply will ease soon. It also gives no support for an across-the-board quarterly price rise or a fixed end date for the shortage. Buyers need contracts for each product and qualified capacity.

Core thesis
NAND has flipped from a commoditising oversupply into an AI-driven structural shortage. Samsung, SK hynix, Micron, Kioxia and Sandisk control supply; the same wafer and capex reallocation toward HBM that boosts DRAM margins is starving NAND capacity just as hyperscaler/AI-server SSD demand surges. Layer-count scaling (300-400+ layers, hybrid bonding) and QLC/PLC density still drive long-run cost, but the near-term story is pricing power, allocation and the emergence of HBF as a new NAND tier for AI.
State of the art (2026)
NAND has flipped from glut to structural shortage. Contract prices jumped roughly 55-75% quarter-on-quarter through H1 2026 as Samsung, SK hynix and Micron reallocated wafers and capex toward HBM for AI accelerators, while hyperscaler SSD demand surged; Kioxia reports its 2026 output already sold out. Supply (15-17% bit growth) trails demand (20-22%), and no meaningful relief is expected before 2027-2028. The technology frontier is hybrid bonding and 300-400+ layers: Samsung's 400-layer V10, Kioxia's 332-layer BiCS10, SK hynix's 321-layer TLC. SK hynix and Sandisk are standardising High Bandwidth Flash (HBF) under OCP, a NAND tier between HBM and SSD, with first samples due H2 2026.
