Renesas has just introduced the industry's first and fastest Gen6 DDR5 RCD for RDIMM modules, offering 9600 MT/s transfer speeds.
Renesas Gen6 DDR5 RCD Enables 9600 MT/s Speeds on RDIMM Modules, Up To 10% Bandwidth Uplift Vs Current-Gen
Press Release: Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, today announced that it has delivered the industry’s first sixth-generation Registered Clock Driver (RCD) for DDR5 Registered Dual In-line Memory Modules (RDIMMs). The new RCD is the first to achieve a data rate of 9600 Mega Transfers Per Second (MT/s), surpassing the industry standard.
Key Features of Renesas’ Gen6 DDR5 RCD
- 10% Bandwidth Increase over Renesas’ Gen5 RCD (9600 MT/s versus 8800 MT/s)
- Backward Compatibility with Gen5 Platforms: Provides a seamless upgrade path
- Enhanced Signal Integrity and Power Efficiency: Enables AI, HPC, and LLM workloads
- Expanded Decision Feedback Equalization Architecture: Offers eight taps and 1.5mV granularity for superior margin tuning
- Decision Engine Signal Telemetry and Margining (DESTM): Improved system-level diagnostics provide real-time signal quality indication, margin visibility, and diagnostic feedback for higher speeds
The new DDR5 RDIMMs are needed to keep pace with the ever-increasing memory bandwidth demands of Artificial Intelligence (AI), High-Performance Compute (HPC), and other data center applications. Renesas has been instrumental in the design, development, and deployment of the new RDIMMs, collaborating with industry leaders, including CPU and memory providers, along with end customers. Renesas is the leader in DDR5 RCDs, building on its legacy of signal integrity and power optimization expertise.
"Samsung has collaborated with Renesas across multiple generations of memory interface components, including the successful qualification of Gen5 DDR5 RCD and PMIC5030,” said Indong Kim, VP of DRAM Product Planning, Samsung Electronics. “We are now excited to integrate Gen6 RCD into our DDR5 DIMMs, across multiple SoC platforms to support the growing demands of AI, HPC, and other memory-intensive workloads."
Availability
The RRG5006x Gen6 RCD is designed to meet the stringent requirements of next-generation server platforms, offering robust performance, reliability, and scalability. Renesas is sampling the new RRG5006x RCD to select customers today, including all major DRAM suppliers. Production availability is expected in the first half of 2027.
