The Rambus NVRCD is the industry’s 1st JEDEC-standard persistent memory register clock driver (NVRCD) in full production for use with NVDIMM-N and emerging NVDIMM-P solutions. This chipset is our complete application-specific standard product (ASSP) solution that is reliable and cost effective. This NVRCD enables persistent memory R-DIMMs and LR-DIMMs operating at speeds up to DDR4-3200.
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.
Persistent memory usage on the DIMM has many use cases for hyperscale, high-performance and high-capacity data centers. These applications include: latency reduction, power reduction, metadata storage, in-memory databases, software-defined server RAID, reduced processing load during unexpected failures and more.
