Abstract
PURPOSE:To strengthen the protection for breakdown of information on a main storage, by checking whether plural storage divices having the same real address have some error or not or securing a normal continuation of process if a correctable erroneous information exists. CONSTITUTION:In case a correction of error is impossible in a mechanism (ECC mechanism) 31 that detects or correct an error and no error is detected or an error can be corrected in an ECC mechanism 30, a selector 34 selcts a new information obtained from the mechanism 30 to send it to a CPU or a channel. At the same time, this information is sent to a memory unit having a correction unable information via a selector 33 to perform a writing action. In such way, the correct information can be sent to the access originator when no error is detected in either one of the mechanisms 30 and 31 or an error correction is possible, and at the same time the information with which an error correction is impossible with use of an error correction code can be restored in a correct way.
