Abstract

PURPOSE: To prevent previously the occurrence of an uncorrectable error and at the same time eliminate a substitute memory, by shifting data in a faulty memory region to a normal region.
CONSTITUTION: When a correctable error is detected 11 in the data within the memory array 9, the type of the error occurred to the memory element is investigated 5. And in case the error is of the prescribed type, the faulty memory region to which the faulty memory element belongs is separated. At the same time, the data stored in the faulty memory region is transferred to an external memory or other region of the array 9.
