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.

address register keeps the track where a given instruction or piece of data is stored in memory.each storage location in memory is identified by an address ,just each house in a street has a address

How does the Fetch Decode Execute work?

The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

What are buffer registers?

A buffer register is the simplest kind of register; all it does is store a digital information temporarily. It holds the contents of the memory which are to be transferred from memory to other components. By acting as a buffer, it allows the central processor and memory units to operate independently without being affected by minor differences in operation. See the related link for more information.
