Micron Technology has completed demonstration and validation of what it described as the world's first 512GB DDR5 RDIMM across multiple server platforms. The module lifts the DDR5 memory capacity ceiling for a single dual-socket server beyond 12TB and is designed for AI inference, in-memory databases and high-density virtualization. Micron said one 512GB module uses more than 60% less operating power than four 128GB modules. AMD and Intel are validating compatibility at speeds of up to 9,200 MT/s, while Micron reported performance gains of up to 1.4 times in certain memory-intensive workloads. Volume production is expected in the second half of 2027 based on customer demand; pricing and a detailed supply schedule have not been disclosed.
