Abstract
To improve the processing efficiency and throughput by performing only a recovery process in read-accessing to a memory even when an address parity error has occurred in write-accessing to the memory, a selector is provided to select one of write data and a parity-bitted address for writing to the memory. If an address parity error has detected, the selector selects the parity-bitted address, in which the address parity error has occurred, instead of write data to be written to the memory during the write-accessing thereto. This address parity error processing method is particularly useful when applied to an information processor, such as a computer system, including a storage (memory).
