Abstract:
A phase change material (PCM) device is disclosed. The PCM device includes a bottom electrode and an insulator layer over the bottom electrode. The PCM device further includes a resistive electrode over the insulator layer with a via in the insulator layer between one end of the resistive electrode and the bottom electrode. The PCM device further includes a PCM region over the resistive electrode and a top electrode over the PCM region.
