Abstract
PURPOSE: To rationally perform error logging and logout, by comparing the failure range detected in the past with that detected at present and delivering the error processing stop signal vased on the result of comparison, in the memory unit with circuit having error detection furnction.
CONSTITUTION: In the memory unit having the function detecting the faulty location of n-bit(n=1,2...), if n-bit error is taken place, the error mode decoder 12 inputting the output of comparators 4-1 to 4-4 judging the range of failure and FF9-1 to 9-4 holding the information for range of failure representing the failed information are provided. Further, the logic circuit by the OR gate with NOT gate delivering the error processing stop signal to the central processor performing suitable processing to the memory error is proveided. Then, the range of failure information at the existing error taken place and that held are compared and if the result of comparison satifies a predetermined condition, the error processing stop signal is delivered.
