The “cutting-edge” Gen4 DDR5 Registering Clock Driver (RCD) from Rambus, a leading semiconductor and silicon IP supplier that speeds up and secures data, is now available. Major DDR5 memory module (RDIMM) manufacturers started receiving samples of the RCD in the fourth quarter of 2023.
By increasing the transmission rate to 7200 MT/s, the Rambus Gen4 RCD would break performance records while providing a “50 percent improvement in memory bandwidth” compared to current DDR5 module solutions that operate at 4800 MT/s. To satisfy the needs of generative AI and other advanced data center workloads, it would support the speed at which server main memory performance is improving. The Rambus 7200 MT/s DDR5 RCD is available today.
“Advanced workloads, led by the breathtaking pace of innovation in AI, are driving an accelerated roadmap of new server platforms for the data center,” said Shane Rau, Vice President, Computing Semiconductors at IDC. “DDR5 RCDs are critical to support the performance, power, and signal integrity required of RDIMMs in AI servers."

Server Performance
To raise the bar for cutting-edge servers’ performance, Rambus DDR5 memory interface chips - such as the RCD, Serial Presence Detect (SPD) Hub, and Temperature Sensors – can prove essential.
With more than 30 years of experience in high-performance memory, Rambus is well-known for its proficiency in signal integrity (SI) and power integrity (PI). This knowledge would make it possible for DDR5 memory interface chips, which provide data center server RDIMMs with better performance and reliability.
"With memory being an essential enabler of server performance, the need for greater memory bandwidth continues its meteoric rise driven by demanding workloads like generative AI,” said Sean Fan, Chief Operating Officer (COO) at Rambus. “The Rambus Gen4 DDR5 RCD is the latest demonstration of our commitment to providing leadership products ahead of the market need to support our customers’ current and planned server platforms.”
