TrendForce says memory vendors’ capacity plans are shifting toward HBM and
high-layer 3D NAND, squeezing mature-node capacity used by NOR Flash and SLC SLC
NAND. With demand stable, cumulative contract prices for both products rose over
100% in 1H 2026; suppliers have no major expansion plans, and TrendForce expects
H2 prices to climb further as supply tightness persists.
