Wikipedia

  1. Memory address register

    In a computer, the memory address register (MAR) is the CPU register that either stores the memory address from which data will be fetched to the CPU registers, or the address to which data will be sent and stored via system bus. In other words, this register is used to access data and instructions from memory during the execution phase of instruction. 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. The MAR register is half of a minimal interface between a microprogram and computer storage; the other half is a MDR. In general, MAR is a parallel load register that contains the next memory address to be manipulated, for example the next address to be read or written.

    A Memory Address Register (MAR) is a hardware component in a computer that stores the address of a specific location in the computer's memory. It is responsible for holding the location in memory to which the Central Processing Unit (CPU) is currently accessing or will be accessing data or instructions. The MAR is an essential component for memory operations, as it allows the CPU to read or write data from or to the correct memory location.
