Abstract:
The disclosure relates to a method for characterizing or measuring a capacitance, comprising: linking the capacitance to a first mid-point of a first capacitive divider bridge, applying to the divider bridge a bias voltage, maintaining the voltage of the first mid-point near a reference voltage, discharging a second mid-point of a second divider bridge in parallel with the first by means of a constant current, and measuring the time for a voltage of the second mid-point to become equal to the voltage of the first mid-point. The disclosure may be applied in particular to the control of a touch screen display.

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.

An embodiment of the present disclosure relates to a method of detection of a touch contact by a sensor including a first step of comparison of a voltage with a first voltage threshold; and a second step of comparison of the voltage with a second voltage threshold, the second step being implemented if the first voltage threshold has been reached within a duration shorter than a first duration threshold, the second voltage threshold being higher than the first voltage threshold.
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.
Abstract:
An integrated circuit memory includes a state transistor having a floating gate which stores a respective data value. A device for protecting the data stored in the memory includes a capacitive structure having a first electrically-conducting body coupled to the floating gate of the state transistor, a dielectric body, and a second electrically-conducting body coupled to a ground terminal. The dielectric body is configured, if an aqueous solution is brought into contact with the dielectric body, to electrically couple the floating gate and the ground terminal so as to modify the charge on the floating gate and to lose the corresponding data. Otherwise, the dielectric body is configured to electrically isolate the floating gate and the ground terminal.
