When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU . When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR . MAR which is found inside the CPU goes either to the RAM (Random Access Memory) or Cache . </P> <P> The Memory Address Register is half of a minimal interface between a microprogram and computer storage .
