Abstract
A programming circuit of a phase change memory cell includes a controllable current generator to supply a programming pulse and an internal control unit coupled to the controllable current generator for stepwise modifying the programming pulse. The internal control unit, in turn, includes a control signal generator to provide the controllable current generator with a plurality of control signals. An oscillator provides a time reference signal and a driving module drives the control signal generator based on the time reference signal. As a result, a programming pulse with stepwise adjustable slope can be produced, including such a pulse with different leading and trailing edges.
