DDR4 shortage tightens as Nanya capacity fills and prices climb

The DDR4 shortage reflects a structural mismatch between legacy infrastructure demand and concentrated DRAM capacity in Taiwan, China—not a transient blip. Despite DDR5 availability, cost barriers and ecosystem inertia keep industrial and server platforms anchored to DDR4, straining mature-node supply. Nanya’s Q3 2026 capacity preemption by anchor clients underscores this dependency. Regulatory scrutiny on semiconductor logistics—though not directly targeting DDR4—elevates compliance overhead. Competitors like Samsung and SK hynix will likely accelerate DDR4 phase-out to prioritize HBM and LPDDR5X, draining liquidity from the commodity segment. Over the next 18 months, DDR4 pricing will plateau at elevated levels, squeezing smaller buyers while hyperscalers secure allocation via advance payments, deepening market bifurcation.
