Abstract

PURPOSE: To secure an automatic correction for a temporary erasion of the memory or a memory erasion due to a partial failure, by providing an error restoring function within a single chip of a semiconductor integrated circuit memory unit. Thus, a high reliability and a compact size can be realized for the memory unit.
