ABSTRACT:
An integrated circuit has been described that includes a user programmable identification code register. The register can be programmed by the user to emulate other integrated circuit devices. The integrated circuit register can also be reset to reflect the original manufacturer information. The integrated circuit can be a memory device and allows the user to upgrade a system while indicating to the original system that the device is compatible.
