Title: System for repair of ROM programming errors or defects

Abstract: A system is disclosed for use of imperfect ROMs in embedded systems. The ROM or other memory accessible upon start-up of the system, includes a stored program which checks an external source to determine whether any of the information in the ROM should be replaced. If it should be replaced, then the system retrieves good information from an external source and stores it into a cache memory. By setting a "lock" bit, erasure of the replacement information is prevented.
