This paper reports bipolar resistive-switching (RS) characteristics and its mechanism observed from Pt/ZrN/Ti capacitors. This ZrN-based RS memory (RSM) shows excellent program/erase behavior under +3 V/10 ns and -3 V/10 ns with a high-to-low resistance ratio of > 104. The device also showed an endurance of > 109 cycles and a retention time of > 10 4s at 85 °C. The temperature-dependent studies of on/off states show that metallic conduction is responsible for on state, whereas semiconducting or insulating behaviors are clearly observed from off -state devices. These results show that ZrN-based RSM can be used as a promising RSM device.
