The Memory Data Register (MDR) holds loaded data so that the memory address can change. ... In this case, we could just keep the address constant by holding the ALU control signals constant, but we want to think in terms of separating the stages ... No enable is required; MDR only needs to hold the data for one clock cycle.

The register-memory architecture is a compromise to the CISC ideal. It covers a range of limitations imposed on a memory-memory architecture. There have been a variety of restrictions that allow at least one memory operand in arithmetic and logical instructions, but require certain operands to ... Instruction Code Size Data...
