  • Integrated circuit (IC) chip comprising an identification circuit
    Patent number: 9941886
    Abstract: An embodiment of the present invention is an identification circuit for generating an identification number (ID). The identification circuit includes a plurality of identification cells each comprising a latch having a first output and a second output that are opposite to each other. The first output and the second output are a function of process variations of the identification circuit. A first buffer and a second buffer are provided on both sides of the latch and connected to the first output and the second output of the latch, respectively.
    Type: Grant
