The Rambus DDR4 RCD is the key control plane chip which distributes Command/Address signals and clock to the DRAM devices on the RDIMM. It provides the speed, reliability and power efficiency required for real-time, memory-intensive applications.
The DB delivers enhanced performance and margin at 2400 Mbps with built-in support for data rates up to 2666 Mbps. This enables the high speeds and robust operation when multiple LRDIMMs populate the memory channel to deliver the highest system capacities.
The Rambus NVRCD provides the RCD functions described above for NVDIMMs which employ non-volatile solid state memories.
