Classification: CPC G  H | IPC H

Claim 11:
12. A driving arrangement for a phase-change material (PCM) switch stack, comprising:
a plurality of PCM switches, each comprising a heater and a volume of PCM, the PCM switches arranged in a stacked configuration;
a plurality of drivers each configured to drive a corresponding PCM switch of the plurality of PCM switches and provide, to a corresponding heater, a first electrical pulse profile or a second electrical pulse profile, depending on a desired state to which the corresponding PCM switch is to be programmed; and
a logic and control module configured to drive the plurality of drivers in separate time intervals, one or more drivers at a time,
wherein, for each time interval, the logic and control module is configured to program the corresponding PCM switch by providing:
a first control pulse to a corresponding driver when the corresponding PCM switch is to be programmed in an ON state in correspondence of the first electrical pulse profile, and
a second control pulse to the corresponding driver when the corresponding PCM switch is to be programmed in an OFF state in correspondence of the second electrical pulse profile.
