TrendForce reports that NOR Flash supply‑demand imbalance will persist through H2 2026, with high‑capacity NOR Flash contract prices potentially rising 90‑110% . AI’s consumption of wafer capacity and rising high‑end demand are constraining bit output growth, and new capacity takes time to qualify – leaving short‑term supply gaps unresolved.
Supplier landscape:
-
Winbond (No. 1 in NOR Flash) leads 2026 bit capacity growth, driven by 45nm ramp and migration to 25nm/20nm – boosting output per wafer without major wafer starts increases.
-
GigaDevice (No. 2) covers 512Kb‑2Gb and is upgrading processes for ≥32Mb products. Some foundry business shifted overseas, pressuring H1 output; H2 capacity is expected to recover.
-
Macronix is prioritizing new 12‑inch capacity for NAND and eMMC, limiting NOR bit growth.
Demand drivers:
-
AI servers consume 3‑5x more NOR Flash than traditional servers. Each Retimer chip requires its own NOR Flash for microcode, driving high‑capacity and Octal SPI NOR demand.
-
Edge AI, AI PCs, and robotics need larger firmware models, further increasing high‑density NOR purchases.
-
LEO satellites and aerospace electronics require high‑reliability NOR for fast boot, firmware backup, and OTA updates – with radiation tolerance and extreme temperature specs limiting supply expansion.
Pricing outlook:
-
H1 2026 NOR contract prices rose 100‑120% .
-
≥256Mb high‑capacity: expected to rise another 90‑110% on AI server and automotive demand plus limited new bit supply.
-
≤128Mb mid‑low capacity: price momentum slowing as some capacity releases; Q4 2026 increase forecast at just 10‑20% , entering a high‑level consolidation phase.
ICgoodFind Takeaway:
High‑capacity NOR Flash is in a clear supply crunch. AI, automotive, and aerospace demand will keep upward pressure on 256Mb+ parts – buyers should monitor fab capacity and pricing closely and plan inventory accordingly.
