BOISE, Idaho, May 12, 2026 – Micron Technology, Inc. (Nasdaq: MU) today announced it has begun sampling its 256GB DDR5 Registered Dual In-line Memory Modules (RDIMMs) to key server ecosystem partners. Based on Micron's leading-edge 1-gamma (1γ) technology, this product achieves speeds of up to 9,200 megatransfers per second (MT/s)*1, over 40% faster than currently mass-produced modules. The module utilizes advanced 3-dimensional stacking (3DS) packaging technology, connecting multiple memory dies with through-silicon vias (TSVs). Combined with Micron's 1γ DRAM, it provides the necessary capacity, speed, and power efficiency for expanding next-generation AI systems. A single 256GB module can reduce operating power by over 40% compared to using two 128GB modules, enabling greater efficiency in today's AI data centers*2.
Ecosystem Partner Validation
Micron is collaborating with key ecosystem partners to validate the 256GB 1γ DDR5 RDIMMs on their current and next-generation server platforms. This joint validation ensures compatibility with a wide range of platforms and accelerates the production deployment process for data center customers building large-scale AI and HPC (High-Performance Computing) infrastructures.
"Capacity, bandwidth, and power are critical factors that determine the efficiency of AI," said Raj Narasimhan, Senior Vice President and General Manager of Micron's Cloud Memory Business Unit. "Micron's 256GB DDR5 RDIMM will significantly enhance server performance. Based on 1γ DRAM with advanced 3DS and TSV packaging, this solution delivers industry-leading speed and power efficiency, helping data center architects scale their AI infrastructure more efficiently."
Meeting Memory Demands in the AI Era
The rapid proliferation of Large Language Models (LLMs), agentic AI, real-time inference, and high-core-count CPU workloads demands greater memory capacity, wider bandwidth, and improved power efficiency from enterprise servers more than ever before. Micron's 256GB DDR5 RDIMM directly addresses these requirements, enabling server architects, hyperscalers, and platform partners to maximize memory capacity per socket within the thermal and power constraints of modern data center infrastructures.
Sampling and Availability
Micron's 1γ-based 256GB DDR5 RDIMMs are now sampling to key server ecosystem partners for platform validation. For more information on Micron's data center solutions, please visit the Micron Data Center Memory webpage.
*1: Performance advantage is calculated by comparing 9,200 MT/s and 6,400 MT/s products.
*2: Operating power is measured in watts. Calculated by comparing two 128GB modules operating at 9.7W each (total 19.4W) with a single 256GB module operating at 11.1W.
