What is Memory Transfer in Computer Architecture?

The transfer of data from a memory word to the external environment is known as a read operation. The read operation in memory transfer is represented as the transfer of data from the address register (AR) with the selected word M for the memory into the memory buffer register (MBR).

[AR]M MBR=Read Operation

The control signal of the read operation starts the read operation. The read operation statement generates the data transfer from the chosen memory register M into the MBR.

The transfer of new data to be saved into the memory is known as the write operation. The memory transfer in the write operation is described as the transfer of data from the memory buffer register (MBR) to the address register (AR) with the chosen word M for the memory.

MBR M [AR] =Write Operation.

The control signal of the write operation starts the write operation. The write operation statement generates the data transfer from the MBR into the chosen memory register through the address shows in the memory M [AR].

It can achieve through a read or write operation, first, the memory register (M) should be selected by a particular address.

The figure shows the memory transfer representation. It demonstrates that the memory unit can transfer the data from the memory address register and memory buffer register to implement read and write operations in the memory transfer.
