How NVRCD for NVDIMM Works
Register Clock Drivers (RCD) buffer and retime command, address, and clock signals from the host CPU. This reduces signal loading on the system controller by isolating the DRAM and is a common practice used in datacenter and other applications where there is an increased need for high-speed memory. Rambus’ NVRCD is the market’s first full-production ASSP clock driver that meets or exceeds all JEDEC DDR4 performance specifications and is operational up to DDR4-3200. It also meets or exceeds all JEDEC RCD2 (rev 93) operation requirements and supports JEDEC LCOM interface which saves FPGA pins usage. This NVRCD is for NVDIMM-N products, which specifically implements non-volatile solid-state memory, such as NAND Flash, and DDR4 DRAM on the same DIMM, but also enables future emerging technologies like NVDIMM-P architectures.
