  2. Memory address register - Wikipedia

    en.wikipedia.org/wiki/Memory_address_register

    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.

  3. Instruction cycle - Wikipedia

    en.wikipedia.org/wiki/Instruction_cycle

    During the fetch stage, the address stored in the PC is copied into the memory address register (MAR) and then the PC is incremented in order to "point" to the memory address of the next instruction to be executed. The CPU then takes the instruction at the memory address described by the MAR and copies it into the memory data register (MDR ...

  4. Memory buffer register - Wikipedia

    en.wikipedia.org/wiki/Memory_buffer_register

    The memory data register is half of a minimal interface between a microprogram and computer storage; the other half is a memory address register (MAR). During the read/write phase, the Control Unit generates control signals that direct the memory controller to fetch or store data.

    # This gives the memory system two clock ticks to fetch the next # instruction to the memory data register for use by the instruction decode. # The sequencer instruction "next" means just add 1 to the control word address. MDR, NONE, MAR, COPY, NEXT, NONE # This places the address of the next instruction into the PC.

  8. Memory address - Wikipedia

    en.wikipedia.org/wiki/Memory_address

    In a computer using virtual memory, accessing the location corresponding to a memory address may involve many levels. In computing, a memory address is a reference to a specific memory location in memory used by both software and hardware. [1] These addresses are fixed-length sequences of digits, typically displayed and handled as unsigned ...
