Rambus Inc. has advanced the performance of its DDR5 registering clock driver (RCD) to 6400 MT/s, which has a 33% increase in data rate and bandwidth over current production intellectual property (IP) cores.
The Rambus 6400 MT/s DDR5 RCD enables a new level of main memory performance for data center servers. The company began shipment samples of the RDIMM to manufacturers in the fourth quarter of 2022.
DDR5 offers enhancements for computing systems as data centers require more and more memory bandwidth. Rambus memory interface chips such as RCD, signal presence detect (SPD) hub and temperature sensors. The DDR5 memory is built into the RDIMMs enabling over double the data rate and four times the capacity of DDR4 RDIMMs. This is at the same time increasing memory and power efficiency.
“Data center workloads have an insatiable thirst for greater memory bandwidth and capacity, and our mission is to advance the performance of server memory solutions that meet this need,” said Sean Fan, chief operating officer at Rambus. “We were first in the industry to 5600 MT/s, and now we have raised the bar with our DDR5 RCD capable of 6400 MT/s supporting a new generation of RDIMMs for server main memory.”
