Abstract
PURPOSE: To grasp assuredly the state of the incidental error by detecting the presence or absence of the error of the data given from the memory device and then displaying the related information.
CONSTITUTION: The data given from the memory device is given to Hamming check circuit 5 to detect the presence or absence of the error. And in case some error is detected, the information concerning the error is displayed 15, 17, 19 and 21 each. Thus the state of error, the area of error, the error address plus the presence and absence of error are displayed respectively. As a result, the state of the incidental error can be grasped in an assured way.
