Abstract

PURPOSE: To increase the reliability of the error detecting/correcting circuit by giving a check to the corrected data through an effective use of the existing circuits.
CONSTITUTION: The data read out from memory unit 1 is supplied to error check circuit 4 via register 2 and data correcting circuit 3. Circuit 4 controls error detecting circuit 5 and checks whether the error can be corrected through correction unable error detecting circuit 6 and correction enable error detecting circuit 7 in case the error takes place. In case the correction enable error occurs, the correction information is set to correction information register 8. At the same time, correction enable error occurrence memory bit 10 is also set. Based on register 8, the error is corrected via correcting position growing circuit 9 and data correcting circuit 8, and the corrected data is delivered to transfer line 19. In this case, whether or not the corrected data is right can be checked by the correction information memorized in register 8
