Abstract

PURPOSE: To enable to correct the data without error in normal operating state, by rewriting the block having error in the buffer storage with priority.
CONSTITUTION: If there is any error in the data readout from the block 3, for example, of the buffer storage 2, the error correcting code check circuit 4 delivers the error signal representing the presence of error to the rewriting order control section 7-1. The least recently used unit 7 makes control so that the rewriting to this block B3 is made with the highest priority, if the data block picked up from the main memory unit 5 is present next. Accordingly, when the data block picked up from the unit 5 is transferred, new data is given to the data block where this error is present. Thus, rewriting to the data without error can be made with comparatively short time.
