MemWrite
MemWrite is a control signal used in a computer processor’s memory subsystem to enable writing data to memory. It is asserted by the control unit during store instructions, such as store word, store byte, or store halfword, to indicate that the data held in the register file should be written to the addressed memory location. MemWrite works in conjunction with the memory interface’s address lines and the memory’s write enable input.
In architectures that support partial-word stores, MemWrite often interacts with byte-enable or write-mask signals that specify
Timing and implementation vary by design. In a simple single-cycle processor, MemWrite may be active during
In hardware descriptions and simulations, MemWrite is represented as a boolean input to the memory block, driven
