Overview
- Micron told investors on its fiscal Q3 2026 earnings call that tightness in high‑bandwidth memory and DRAM will persist well into 2028 and that its new Idaho fab will not reach meaningful volumes until 2028.
- Market research group TrendForce projects HBM wafer input will climb to about 30% of total DRAM wafer input by the end of 2027, which cuts capacity available for conventional DRAM.
- HBM production uses more advanced process steps and more wafer area per chip than standard DDR memory, so every wafer devoted to HBM reduces conventional DRAM output and raises prices.
- Suppliers are prioritizing HBM, shifting production mix toward data‑center chips and locking buyers into long‑term contracts, a strategy that has preserved margins while tightening spot supply.
- Major customers including Apple are quietly exploring alternative memory strategies and architectures, a move that could reshape future supplier shares, affect cloud GPU costs, and increase interest in decentralized compute options.
