Renesas Electronics Corporation is rolling out its (Gen 3) DDR5 MRDIMM chipset solutions, pushing server-class memory speeds to 16,000 MT/s. The move comes as AI data centers, cloud infrastructure, and accelerated compute workloads demand ever-higher memory bandwidth.
What’s New in Gen 3
The new chipset delivers 25% more memory bandwidth than Renesas’ second-generation Multiplexed Rank Dual In?Line Memory Module (MRDIMM) solutions, without requiring a complete overhaul of existing DDR5 server platforms.
That means system architects can extract more performance from their current infrastructure instead of starting from scratch.
At the core of the Gen 3 lineup are the Multiplexed Registering Clock Driver (MRCD, RRG5013) and Multiplexed Data Buffer (MDB, RRG5103) devices, both engineered to support next-generation MRDIMM performance while maintaining standard DIMM form factors.
Built for AI Workloads
As AI models grow larger and more data-hungry, memory bandwidth has become a critical bottleneck.
Renesas’ approach addresses this by extending the proven MRDIMM architecture introduced with Gen 2, adding enhancements like Device Equalization Self-Train Mode (DESTM) Quality Indication Status. This feature lets engineers fine-tune timing and receiver equalization training to maximize system margins.
The company also designed Gen 3 with power efficiency in mind, helping customers balance rising bandwidth demands against thermal and power constraints at the system level. Detailed power comparisons will be available in the accompanying product documentation.
Full Platform Support
Renesas isn’t just shipping individual chips, it says to offer a complete, production-ready MRDIMM platform that includes MRCD, MDB, Power Management ICs (PMIC), Serial Presence Detect (SPD) Hubs, and temperature sensors.
This platform approach is known to enable customers to scale MRDIMM performance across generations while maintaining design continuity and accelerating deployment.
Where to See It
Renesas will showcase its Gen 3 MRDIMM memory interface components at FMS 2026 (Future of Memory and Storage Conference) in Santa Clara, California, August 4-6, 2026, at Booth #807.
The company is working closely with leading CPU and platform partners to enable MRDIMM Gen 3 adoption in future server platforms, positioning MRDIMM as a scalable memory architecture for next-generation AI and cloud infrastructure.
Leadership Comments
“AMD has a long history of supporting open, standards-based technologies that power data center innovation and deliver greater flexibility as AI and HPC workloads continue to evolve,” said Amit Goel, Corporate Vice President, Compute and Enterprise AI Platform Solutions Engineering, AMD. “Innovations in next-generation memory form factors such as MRDIMM and Renesas’ chipset are important to helping the industry deliver higher bandwidth, greater efficiency and continued platform scalability.”
“AI training and inferencing workloads are fundamentally reshaping system memory requirements for data center infrastructure,” said Sameer Kuppahalli, Vice President and General Manager, Memory Interface Division at Renesas. “To meet the insatiable appetite of these workloads for memory capacity and throughput, Renesas continues to lead the industry by delivering our 3rd generation of chipset components for MRDIMM. Our customers employ Renesas’ complete chipset components in order to further push the frontiers of memory throughput and capacity.”
Availability
Renesas MRDIMM Gen 3 MRCD (RRG5013x) and MDB (RRG5103x) are sampling to select customers today, including all major DRAM suppliers. Production availability is expected in 2H/2027.
