Contract prices surged over 100% in 1H26; Structural shortages to keep NOR Flash and SLC NAND prices rising in 2H26

This has squeezed the mature-node capacity for NOR Flash and SLC NAND. Against a backdrop of steady demand, cumulative contract price increases for both product categories exceeded 100% during the first half of 2026.
