Rambus Announces Availability of Gen 4 DDR5 Registering Clock Driver

Rambus Inc., a leading chip and silicon IP provider, has announced the availability of its state-of-the-art Gen 4 DDR5 Registering Clock Driver (RCD). The RCD has begun sampling to major DDR5 memory module manufacturers in the fourth quarter of 2023. This new RCD boosts the data rate to 7200 MT/s, setting a new performance benchmark and enabling a 50% increase in memory bandwidth compared to current DDR5 module solutions.

The Rambus Gen 4 RCD supports the rapid pace of server main memory performance improvements, specifically to meet the demands of generative AI and other advanced data center workloads.

"With memory being a crucial factor in server performance, the need for greater memory bandwidth continues to rise, driven by demanding workloads like generative AI," said Sean Fan, Chief Operating Officer at Rambus. "The Rambus Gen 4 DDR5 RCD demonstrates our commitment to providing leadership products that support our customers' current and future server platforms."

"Advanced workloads, particularly the rapid innovation in AI, are driving the development of new server platforms for data centers," said Shane Rau, VP, Computing Semiconductors at IDC. "DDR5 RCDs are critical in supporting the performance, power, and signal integrity required for RDIMMs in AI servers."

Rambus DDR5 memory interface chips, including the RCD, Serial Presence Detect (SPD) Hub, and Temperature Sensors, play a crucial role in achieving high performance for cutting-edge servers. With over 30 years of experience in high-performance memory, Rambus is known for its expertise in signal integrity (SI) and power integrity (PI). This expertise enables DDR5 memory interface chips to deliver superior performance and reliability for data center server RDIMMs.

The Rambus 7200 MT/s DDR5 RCD is available now.
