Rambus Inc. announced the release of its Gen4 DDR5 Registering Clock Driver (RCD), now in sampling phase for major DDR5 memory module manufacturers. This RCD enhances data rate to 7200 MT/s, achieving a 50% increase in memory bandwidth over current 4800 MT/s DDR5 module solutions. It aims to support advancements in server main memory performance, particularly for demanding workloads like generative AI in data centers and reliability for data center server RDIMMs.
The Rambus DDR5 memory interface chipset, comprised of DDR5 Registering Clock Drivers (RCD), Serial Presence Detect Hubs (SPD Hub), and Temperature Sensors (TS), caters to the performance needs of advanced DDR5 memory systems and Non-volatile memory DIMMs (NVDIMMs). Designed for high capacity and bandwidth, these chips empower both server and client computing systems to manage intensive workloads and applications. Additionally, the SPD Hub facilitates DDR5 Unbuffered DIMMs (UDIMMs) and Small-Outline DIMMs (SODIMMs) for PC clients.
Features:
- The RCD manages Command/Address signals and clock distribution to DRAM devices on the RDIMM.
- The SPD Hub communicates vital system configuration and thermal data through the I3C bus and includes an integrated temperature sensor.
- Two TS per DIMM provide precise thermal sensing, offering three points of thermal telemetry for the memory module along with the SPD Hub.
