Classification: CPC G  H | IPC H

Claim 12:
13. A method of programming a state of a phase change material (PCM) switch, the PCM switch comprising a heater and a volume of a PCM, the method comprising:
providing a driver circuit;
integrating the driver and the PCM switch on the same chip;
applying a first control pulse to the driver circuit when the PCM switch is to be programmed in an ON state;
applying a second control pulse to the driver when the PCM switch is to be programmed on an OFF state;
through the driver circuit, applying a first driver pulse, in correspondence with the first control pulse, to the PCM switch;
through the driver circuit, applying a second driver pulse, in correspondence with the second control pulse, to the PCM switch, and, wherein:
an amplitude of second control pulse is greater than an amplitude of the first control pulse, and
a width of the second control pulse is shorter than a width of the first control pulse.
