ABSTRACT:
A memory system includes manufacturer identifiers, such as serial numbers and part numbers, stored in locations of memory that are unalterable by end users. A customer identification location of the memory allows the user to program its own identifier and includes a locking code that prevents subsequent alteration of the customer identification location. A recall procedure at power on verifies the content of the locked code for allowing alteration of the memory.
