Micron 256GB SOCAMM2 Memory Samples for AI Servers
Micron developed the first 256GB SOCAMM2 memory samples which they sent to AI server markets. Micron Technology revealed its 256GB SOCAMM2 memory module through customer sample shipments on March 3 2026. The release introduces the maximum available capacity for LPDRAM modules. The hardware operates through the industry’s first monolithic 32Gb LPDDR5X design which engineers created to handle the enormous memory requirements of AI training and inference and high performance computing (HPC).
The 256GB SOCAMM2 memory module delivers solutions to the existing "memory bottleneck" problem which occurs in contemporary AI workloads that require high bandwidth and low latency due to their extensive model parameters and large context windows. Micron achieved higher density through the usage of 32Gb monolithic die technology without losing the power saving benefits that LPDRAM technology delivers.
The memory has been optimized by Micron to work with new AI infrastructure systems through their partnership with NVIDIA. Ian Finder from NVIDIA Data Center CPU Product management said that SOCAMM2 architecture provides essential capacity and bandwidth requirements for upcoming AI processors.
The SOCAMM2 form factor provides multiple benefits when compared to existing RDIMM (Registered DIMM) systems used in servers.
- Power and Space Efficiency: The SOCAMM2 modules consume only one third of the power required by equivalent RDIMMs while occupying only one third of the physical footprint. This allows for significantly higher rack density in data centers.
- The 256GB SOCAMM2 system reduces "time to first token" for real time Large Language Model (LLM) inference with long context windows by more than 2.3 times when compared to current solutions.
- Performance Per Watt: The modules offer triple the power efficiency of typical memory products in CPU applications which function independently.
- The 8 channel CPU now enables support for 2TB of LPDRAM which allows users to run advanced inference tasks together with persistent key value (KV) caching.
The SOCAMM2 system uses a modular structure that enables simple server maintenance while maintaining essential performance requirements for liquid cooled systems. Data center operators can use this solution which permits memory capacity growth to match new AI demands. Micron helps establish the JEDEC standard for low power modular memory through its participation in the specification process.
Micron provides data center solutions which include 8GB components and the new 256GB SOCAMM2 modules to system designers who require AI and general purpose computing components.
