Micron Announces DDR4 Sunset Amid Stronger‑Than‑Ever Demand

Micron has informed its customers that its DDR4 memory products will reach the end of life in the coming quarters, with shipments expected to taper off over the next six to nine months. This announcement aligns Micron with the earlier plans of Samsung and SK Hynix to discontinue DDR4 production and focus on next-generation memory solutions, such as DDR5, LPDDR5, and high-bandwidth memory. In a recent interview, Micron’s Executive Vice President and Chief Business Officer, Sumit Sadana, acknowledged that the phase‑out comes at a time when demand for DDR4 remains unexpectedly strong. He noted that shortages of both DDR4 and LPDDR4 modules have driven spot-market prices to levels that, in some cases, exceed those of newer DDR5 products.

To address this imbalance, Micron will prioritize supply for long‑term partners in the automotive, industrial, and networking sectors, where product reliability and contract stability are critical. The retirement of DDR4 has been partly driven by competitive pressure from Chinese memory manufacturers, which have flooded the market with lower‑cost modules. Yet, these newcomers may face challenges in matching the quality, long-term support, and volume capabilities that established players provide. Micron is urging its customer base to transition to DDR5 and LPDDR5 products, which have reached competitive price points and offer superior bandwidth and energy efficiency.
