Abstract

The present invention provides a memory architecture that allows memory checking and replacement of defective words by spare elements already provided on the chip that do not increase the chip size. The method of the invention uses a separate redundant array architecture to provide address translation, so that the redundant entries are represented as the correct entry index that they are replacing.
