Abstract

PURPOSE:To improve the accuracy of fault analysis by informing an operating system or a user of whether a checking circuit is correct or not during retrying operation. CONSTITUTION:During retrying operation, checking circuits 12-1-12-n detect an error. In this case, when test data is insignificant, processing which corresponds to a failure in retrying is performed and when significant, test data which corresponds to one of the checking circuits 12-1-12-n which has detected the error is read out of a storage circuit 7. Then, a test input is supplied to the input points 11-1-11-n of the checking circuit and the values of the output points 13-1-13-n of the checking circuit are compared with the normal values of the test data of the checking circuits for the test input to send coincidence/dissidence signals 30 to an error informing circuit 15, thus letting an operating system or a user know those through signal lines 31-1-31-n.
