Micron, an American semiconductor giant and market leader in memory and storage, has unveiled the world’s first ultra-dense memory module for next-generation servers.

Micron claims this new 512GB DDR5 RDIMM unlocks speeds of up to 9,200 MT/s while reducing operating power consumption by more than 60%.

This marks a major milestone, as it is the first 512GB DDR5 module of its kind and has already been successfully demonstrated across multiple server platforms.

Micron has stated that both AMD and Intel are currently validating the new module for their respective server platforms.

This engineering feat was made possible by Micron’s advanced vertical interconnect packaging innovations. The technology allows for the vertical stacking of DRAM dies, which are interconnected by through-silicon vias (TSVs) to maximize density within individual packages. When fully implemented, these modules allow a single 24-slot, dual-socket server to support a massive 12TB of DDR5 RAM.

“Micron continues to set the pace for memory technology, delivering a new class of ultra-dense, high-performance server memory that helps customers keep larger datasets closer to the compute engines that need them,” said Raj Narasimhan, senior vice president and general manager of the Cloud Memory Business Unit at Micron. “A 512GB RDIMM enables multi-terabyte servers, supporting larger AI and database workloads, greater virtualization density and improved power efficiency, all within existing server footprints.”

This announcement comes at a critical time. The rapid deployment and expansion of AI models (LLMs), performance-sensitive inference jobs, and agentic workflows are driving an unprecedented demand for larger server memory capacities.

Micron expects these modules to enter mass production during the second half of 2027.
