Renesas Electronics Corporation has unveiled its third-generation DDR5 Multiplexed Rank Dual In-Line Memory Module (MRDIMM) chipset, which offers server-class speeds reaching 16,000 mega transfers per second (MT/s). The Gen 3 chipset delivers a 25% increase in memory bandwidth over its second-generation counterpart while maintaining compatibility with existing DDR5 infrastructure.
Key components include the third-generation Multiplexed Registering Clock Driver (MRCD, RRG5013) and Multiplexed Data Buffer (MDB, RRG5103). Renesas will present these innovations at the Future of Memory and Storage Conference in Santa Clara, California, from August 4-6, 2026.
This platform is designed to enhance system efficiency and performance in data centers, particularly for AI workloads. The Gen 3 solution retains standard DIMM form factors and improves signal quality through Device Equalization Self-Train Mode (DESTM) Quality Indication Status. Renesas is collaborating with leading CPU and platform partners to facilitate the adoption of MRDIMM Gen 3 in future server platforms.
