Recently, many kinds of next-generation nonvolatile memories, such as resistive random access memory and phase change memory, have attracted a lot of attention. Because of the RRAM possesses the bistable conductivity switching characteristics, the device can exhibit two different conductivities at the same applied voltage. In addition, the RRAM with high operation speed, nondestructive readout, and simple device structure are helpful for high density of integration and lower power consumption. Therefore, the RRAM has been proposed to be a possible candidate of next-generation nonvolatile memories.
