As one of emerging next-generation nonvolatile memories, Resistive RAM (ReRAM) still calls new material technology to improve its performance. By utilizing the special characteristics of cerium oxides, this paper proposes a new method to improve the performance of CeO2 based ReRAM devices by using Si buffer layer. It is confirmed that the device having W/CeO 2/Si/TiN structure shows significant advantage over the device without Si layer for memory application in terms of lower forming voltage, smaller compliance current, larger window and better endurance characteristic. The effect of Si buffer layer is discussed in detail and a model based on filament switching mechanism was also proposed to explain the underlying reasons.
