Abstract: An integrated circuit includes a memory cell incorporating an antifuse device. The antifuse device includes a state transistor having a control gate and a second gate that is configured to be floating. A dielectric layer between the control gate and the second gate is selectively blown in order to confer a broken-down state on the antifuse device where the second gate is electrically coupled to the control gate for storing a first logic state. Otherwise, the antifuse device is in a non-broken-down state for storing a second logic state.

Abstract: An integrated circuit includes a first substrate. A MOS transistor has a first polysilicon region electrically isolated from the first substrate and including a gate region. A second polysilicon region is electrically isolated from the first polysilicon region and from the first substrate. The second polysilicon region includes a source region, a substrate region and a drain region of the MOS transistor. The first polysilicon region is located between an area of the first substrate and the second polysilicon region.

Abstract: Control over the operation of an electrically-controlled motor is supported by an interface circuit between the electrically-controlled motor and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

Abstract: A cryptographic circuit performs a substitution operation of a cryptographic algorithm. For each substitution operation of the cryptographic algorithm, a series of substitution operations are performed by the cryptographic circuit. One of the substitution operations of the series is a real substitution operation corresponding to the substitution operation of the cryptographic algorithm. One or more other substitution operations of the series are dummy substitution operations. A position of the real substitution operation in said series is selected randomly.
