Renesas Electronics Corporation has unveiled its third-generation (Gen 3) DDR5 Multiplexed Rank Dual In-Line Memory Module (MRDIMM) chipset solutions, capable of achieving 16,000 MT/s DDR5 server-class speeds. These new solutions are engineered to meet the escalating demand for enhanced memory bandwidth, crucial for AI data centers, cloud infrastructure, and intensive compute workloads.

Renesas will showcase these advancements, including the third-generation Multiplexed Registering Clock Driver (MRCD) and Multiplexed Data Buffer (MDB) devices, at FMS 2026 in Santa Clara, California. The Gen 3 MRDIMM solutions offer a 25 percent increase in memory bandwidth compared to their predecessors, while maintaining compatibility with existing DDR5 infrastructure, allowing server platforms to boost performance without significant architectural overhauls.

This platform approach, encompassing MRCD, MDB, PMICs, SPD Hubs, and temperature sensors, enables customers to scale MRDIMM performance across generations with design continuity. Features like Device Equalization Self-Train Mode (DESTM) Quality Indication Status enhance system visibility and robustness. The solutions also prioritize system-level power efficiency. AMD, through Amit Goel, and Renesas, through Sameer Kuppahalli, highlight the importance of these innovations for future data center scalability and efficiency. Sampling is underway, with production availability anticipated in 2H/2027.
