Renesas has introduced the third generation DDR5 registered clock driver (RCD), plus the first-generation client clock driver (CKD) for emerging DDR5 DRAM servers and client systems
The ICs enable next generation DIMMs with speeds up to 6400 and 7200 mega transfers per second (MT/s) respectively, an increase from today’s 5600 MT/s transfer speeds. The RCD is designed for registered DIMMs (RDIMMs), while the CKD supports speeds up to 7200 MT/s and is the first to interface with small-outline DIMMs (SODIMMs), unbuffered DIMMs (UDIMMs), high- performance gaming DIMMs and memory down applications for client platforms.
Renesas’ corporate VP and GM of the advanced mixed signal and ASIC solutions division, Balaji Kanigicherla, said: “By playing an integral role in defining and implementing DDR5 interface specifications, Renesas continues to be an important partner for the world’s leading SOC and DRAM players for DIMM and system-level bring up.”
Intel’s VP of memory and IO technologies, Dr Dimitrios Ziakas, added: “Intel Xeon- based platforms are designed to support memory intensive usages like predictive analytics that use deep learning and machine learning. Gen 3 RCD is a major milestone for the memory industry to help meet the bandwidth and scaling capacity needs of our datacenter customers.
“The client clock driver is a new industry initiative to further enhance the client DIMM. Renesas and Intel have been collaborating with the industry to help ensure specification and implementations of the Gen 3 RCD and client clock driver to meet the market needs.”
