What is Destination memory address register?

The Destination Memory Address Register (DMAR) is a hardware component in a computer's memory management system that holds the address of the memory location where data is to be written. It is used during data transfer operations to specify the target address for incoming data. By separating the destination address from the data itself, the DMAR facilitates efficient memory access and management during instruction execution. This is particularly important for operations involving direct memory access (DMA) and other data handling processes.
