描述
The RG5D188 (MDB) is an MCR DIMM Data Buffer. Its primary function is to demultiplex and buffer data from the host CPU to DRAMs. It has two 4-bit data interfaces to the host, running at twice the speed of the DRAM interfaces. Each host interface multiplexes two pseudo-channels, both of which have a separate 4-bit DRAM interface. The RG5D188 supports x4 or x8 DRAMs. It also has an input-only control bus interface that is connected to an MRCD, as well as a dedicated pin for ZQ Calibration and loopback outputs for test purposes.
