SpletRegister memory is the smallest and fastest memory in a computer. It is not a part of the main memory and is located in the CPU in the form of registers, which are the smallest data holding elements. A register temporarily holds frequently used data, instructions, and memory address that are to be used by CPU. SpletThe control unit sends out a memory read signal, and the contents of the address 0000 are copied through the data bus to the memory data register (MDR). As the data fetched during the fetch stage is an instruction, it is copied into the instruction register (IR).
