  • Patent number: 12289884
    Abstract: A bipolar transistor includes a common collector region comprising a buried semiconductor layer and an annular well. A well region is surrounded by the annular well and delimited by the buried semiconductor layer. A first base region and a second base region are formed by the well region and separated from each other by a vertical gate structure. A first emitter region is implanted in the first base region, and a second emitter region is implanted in the second base region. A conductor track electrically couples the first emitter region and the second base region to configure the bipolar transistor as a Darlington-type device. Structures of the bipolar transistor may be fabricated in a co-integration with a non-volatile memory cell.

    Abstract: Unclonable function circuitry includes a plurality of pairs of phase-change memory cells in a virgin state, and sensing circuitry coupled to the plurality of pairs of phase-change memory cells in the virgin state. The sensing circuitry identifies a subset of the plurality of pairs of phase-change memory cells in the virgin state based on a reliability mask. Signs of differences of effective resistance values of the identified subset of the plurality of pairs of phase-change memory cells in the virgin state are sensed by the sensing circuitry. The sensing circuitry generates a string of bits based on the sensed signs of differences in the effective resistance values of the identified subset of the plurality of pairs of phase-change memory cells in the virgin state. Processing circuitry coupled to the unclonable function circuitry, in operation, executes one or more operations using the generated string of bits.
