DDR4 RDIMM
M88DDR4RCD01 (Gen1 DDR4 RCD)
M88DDR4RCD01 is a 32-bit 1:2 configurable Gen1 DDR4 Registering Clock Driver (RCD) with parity check for DDR4 RDIMM and LRDIMM applications. The RCD is compliant with JEDEC DDR4RCD01 specification, supports data rates up to 2400 MT/s and VDD supply of 1.2 V. By buffering the command, address, control, and clock signals of the memory channel, the chip reduces the load of the memory controller and enhances the signal integrity, thereby boosting the capacity and bandwidth of the memory system.
The left image shows the application of RCD on the DDR4 RDIMM as an example.
