ABSTRACT:
A memory management unit is capable of judging that a specific bit has been partially rewritten by checking it against a dummy bit stored in a tag memory which is included in the memory management unit and thus correcting a parity bit. Accordingly, it is possible to accurately execute a parity check operation and it is also possible to improve the throughput of the memory management unit and hence promote lowering in the cost.
