Memory Address Register

Encyclopedia : M : ME : MEM : Memory Address Register

The Memory Address Register or MAR is the register of a computer's control unit that contains the address of a register to fetch or store from or to the computer storage.

The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register.

Far more exotic memory interfaces exist, but this is the least that can work.
