Abstract: An electronic switch may include transfer transistor having a first conduction terminal for receiving an input signal, a second conduction terminal, and a control terminal. The transfer transistor may enable/disable a transfer of the input signal from the first conduction terminal to the second conduction terminal according to a control signal. The control signal may take a first value and a second value different from the first value, a difference between the first value and the second value defining, in absolute value, an operative value of the control signal. The electronic switch may further comprise a driving circuit for receiving the input signal and the control signal, and for providing a driving signal equal to the sum between the input signal and the operative value of the control signal to the control terminal of the transfer transistor.

Abstract: A driving stage for a phase change non-volatile memory device may include an output driving unit, which supplies an output driving current during programming of a memory cell, a driving-control unit, which receives an input current and generates a first control signal for controlling supply of the output driving current in such a way that a value thereof has a desired relation with the input current, and a level-shifter element, which carries out a level shift of a voltage of the first control signal for supplying to the output driving unit a second control signal, having a voltage value that is increased with respect to, and is a function of, the first control signal. A calibration unit may carry out an operation of updating of the value of a shift voltage across the level-shifter element, as the value of the input current varies.
