Array architecture for large scale integration of phase-change material (PCM) radio frequency (RF) switches

An array includes a shared pulse generator and a plurality of cells. A selected cell the plurality of cells includes a phase-change material (PCM) and a heating element, the heating element being transverse to the PCM. The array further includes a row selector configured to connect the shared pulse generator to the selected cell, and a selector configured to connect the selected cell to a ground. The shared pulse generator provides an electrical pulse to cause the heating element in the selected cell to generate a heat pulse. In one approach, the selected cell also includes a non-linear device such as a diode, and the shared pulse generator provides the electrical pulse to a PCM RF switch of the selected cell through the non-linear device to change a state of the PCM RF switch.
