what do we name to an address that is loaded into the memory-address register of the memory
Memory address 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. MAR which is found inside the CPU goes either to the RAM(Random Access Memory) or Cache.
