NOR Flash and SLC NAND Shortages Push Prices Higher

The 2026 memory squeeze is no longer only a DRAM, HBM or high-capacity NAND story. Mature NOR flash and single-level-cell NAND are also in structural undersupply as manufacturers direct wafer capacity and investment toward products with higher revenue potential.

TrendForce reported in June that average contract prices for NOR flash and SLC NAND had each risen by more than 100% during the first half of 2026. Its estimates put the first-half increase at roughly 100–120% for NOR flash and 130–150% for SLC NAND. More recent industry reporting says the same supply pressure remains in place rather than resolving during the second half.

The shortage has an economic cause as much as a technical one. TrendForce says major memory suppliers are prioritizing HBM and advanced-layer 3D NAND while mature-node NOR and SLC capacity remains constrained. In SLC NAND, some international suppliers have also been reducing their exposure to low-capacity mature products.

That creates an awkward market. NOR and SLC devices are inexpensive relative to cutting-edge memory, but many of the products using them have long qualification cycles and cannot substitute another component overnight. Recent reporting from Tom’s Hardware cites TrendForce research manager Bryan Ao saying mainstream NAND can generate far more revenue from a 12-inch wafer than SLC NAND, weakening the incentive to dedicate scarce manufacturing resources to SLC.

NOR flash commonly stores firmware and boot code, while true SLC NAND is valued for endurance and reliability in networking, industrial, automotive and other embedded equipment. Those markets overlap with the infrastructure around PCs even when the user’s NVMe drive itself uses TLC or QLC NAND.

For PC hardware, the near-term risk is therefore broader component cost and availability rather than a simple one-to-one increase in consumer SSD prices. Motherboards, networking hardware, storage appliances and peripherals all depend on embedded controllers and firmware storage. A small flash component can become a production constraint if an approved replacement is unavailable, even when its share of the bill of materials is modest.

TrendForce said suppliers had no significant mature-flash capacity expansion plans and expected high-density NOR flash and SLC NAND prices to continue rising through the second half of 2026. It also expects suppliers to rely more on long-term supply agreements and selective order acceptance as availability tightens.

Those projections should be treated as forecasts rather than guaranteed price outcomes. Demand can weaken, suppliers can reallocate output, and Chinese or Taiwanese producers can add supply at the margin. What is already established is the first-half price surge and the capacity shift away from mature flash; the size and duration of the next increase remain market-dependent.
