Patent ID: 8322626

Claim:
An integrated circuit (IC) die comprising: a high capacitance solid state circuit region configured to perform predetermined operations; a RFID block comprising a FeRAM block for storing data; an interface unit configured to transfer to the RFID block an externally-provided unique ID for wirelessly identifying the IC die, the interface unit being further configured to enable communication between the RFID block and the high capacitance solid state circuit region, the RFID block being further configured to generate an internal BIST (built-in self test) command in response to an external command received by the RFID block directly through the high capacitance solid state circuit region; and a conductive trace extending through predetermined regions of the IC die, the conductive trace being configured as an antenna for the RFID block, wherein the RFID block is configured to receive and transmit information to an external source via the antenna; wherein the FeRAM block stores the unique ID, at least part of test results performed in the IC die, and tracking information in the IC die, the tracking information identifying manufacturing plant in which the IC die is manufactured and process technology used to manufacture the IC die.
