Memory Makers Prioritize HBM Over Consumer RAM
7.0
Veteran memory executive Dave Eggleston told the Broken Silicon Podcast recently that DRAM makers are reallocating capacity to high-bandwidth memory (HBM) for AI accelerators, tightening consumer DDR4/DDR5 supply. He casts doubt on claims that OpenAI locked 40% of HBM, explains wafer-banking flexibility, and forecasts relief after 2026 as 8–10 new DRAM fabs and 3D DRAM ramp production.
Key Points
- 1Explains memory makers shifting capacity to HBM, reducing DDR4/DDR5 consumer RAM supply.
- 2Notes OpenAI wafer LTAs likely PR-driven and nonbinding, limiting their long-term market impact.
- 3Predicts shortages easing after 2026 as 8–10 new DRAM fabs and 3D DRAM ramp.
