Abstract: In accordance with an embodiment, a physically unclonable function device includes a set of transistor pairs, transistors of the set of transistor pairs having a randomly distributed effective threshold voltage belonging to a common random distribution; a differential read circuit configured to measure a threshold difference between the effective threshold voltages of transistors of transistor pairs of the set of transistor pairs, and to identify a transistor pair in which the measured threshold difference is smaller than a margin value as being an unreliable transistor pair; and a write circuit configured to shift the effective threshold voltage of a transistor of the unreliable transistor pair to be inside the common random distribution.

Abstract: A power supply voltage is monitored by a monitoring circuit including a variable current generator and a band gap voltage generator core receiving the variable current and including a first node and a second node. A control circuit connected to the first and second nodes is configured to deliver a control signal on a first output node having a first state when an increasing power supply voltage is below a first threshold and having a second state when increasing power supply voltage exceeds the first threshold. The first threshold is at least equal to the band gap voltage. An equalization circuit also connected to the first and second nodes with feedback to the variable current generator generates the bandgap voltage at a second output node. The control signal operates to control actuation of the equalization circuit.

Abstract: A charge pump circuit can be controlled by a control signal that is generated from a first signal coming from and output signal of the charge pump circuit, from a reference signal, and from a clock signal. The generation of the control signal includes a comparison of the reference signal and of the first signal in tempo with a timing signal coming from the clock signal.

Abstract: A non-volatile memory is erasable by page and equipped with a row redundancy mechanism. In the case of the detection of a defective row of the memory plane, the storing of the address of the row in a non-volatile register is carried out and a redundant row having a new address is assigned. In the case of an attempt to write to the defective row, a write to the redundant row is carried out. When writing to the redundant row, the new content of the redundant row is loaded into a volatile memory and, following an operation for writing to any other row of the memory plane, a re-loading of the new content of the redundant row into the volatile memory.
