Abstract:
1. A driving stage for a phase change non-volatile memory device, the driving stage comprising: an output driving unit configured to supply an output driving current during an operation of programming of at least one memory cell of the phase change non-volatile memory device; a driving-control unit configured to receive an input current and to generate on a control output a first control signal configured to control supply of the output driving current by said output driving unit in such a way that a value of the output driving current is based upon the input current; and a level-shifter between the control output of said driving-control unit and a control input of said output driving unit, and configured to determine a level shift of a voltage of the first control signal for supplying to said control input of said output driving unit a second control signal having a voltage value that is increased with respect to, and is based upon the first control signal.
