Abstract

PURPOSE:To secure the error retrieval of a main memory through simple constitution, by storing an error detection signal in a storage bit of an address array and by specifying corresponding information to be moved out. CONSTITUTION:If an error from information moved in from a main memory 2 is detected by the error correcting circuit 5 of an information processor 1, an error detection signal is applied to the storage bit S of an address array 4 via an OR circuit 6 applied with a storage indication. Consequently, information, wherein the error occurs, from the memory 2 is corrected as an object to be moved out without reference to the generation of the storage indication to write the corrected information in a buffer memory 3, and consequently the error of the main memory is retrieved with simple constitution, thereby improving the reliability of the information processor.
