MAR (Memory Address Register) holds the address of the memory location to be accessed or written to in the memory unit, whereas MDR (Memory Data Register) holds the actual data that is to be written to a memory location or data read from a memory location. MAR is used to specify the address, while MDR is used to temporarily store the data during memory operations.

Function of a MAR and MDR?

The Memory Address Register (MAR) holds the memory address that is currently being accessed or written to in the memory. The Memory Data Register (MDR) holds the data that is being read from or written to the memory at the address stored in the MAR. Together, the MAR and MDR facilitate the communication between the CPU and memory in a computer system.


How do the contents of the MAR and MDR registers changes during the fetch decode execute cycle?

During the fetch-decode-execute cycle, the Memory Address Register (MAR) holds the address of the memory location from which data is to be fetched or to which data is to be written. In the fetch phase, the MAR is loaded with the address of the next instruction to be executed. The Memory Data Register (MDR) then temporarily holds the data fetched from memory or the data to be written to memory. As the cycle progresses, the contents of the MAR and MDR are updated based on the memory operations required for executing the instruction.

What are the Functions of the memory buffer register?

In other words, MAR holds the memory location of data that needs to be accessed. 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. 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 complex memory interfaces exist, but this is the least that can work.
