Abstract

A method for utilizing a cyclical redundancy check value with an identification field stored in memory which is constantly changing between testing of the cyclical redundancy check value. In order to allow the use of a cyclical redundancy check value with a field which constantly varies as does the field in a flash EEPROM memory array, various portions of the field are masked to the cyclical redundancy check and additional reliability checks are utilized to assure that those portions which are masked remain reliable.
