METHOD AND APPARATUS FOR SERIALIZING MICROPROCESSOR IDENTIFICATION NUMBERS

摘要

A method and apparatus for providing a microprocessor serial number. A small, nonvolatile random access memory is packaged with the CPU die to provide a storage space for a CPU serial number which can be programmed before leaving the factory. Both the CPU die and the nonvolatile RAM die reside within the cavity of the package. Connection between the two dies is provided by conventional wire bonding.
