Self-rectifying using a pure HfO2 layer with asymmetric structure was realized in Pt/HfO2/n+-Si resistive random access memory (RRAM). The device exhibits repeatable self-rectifying behavior with high rectifying ratio (>105). The electrostatic effect induced by the asymmetric structure of the HfO2 layer is responsible for the rectifying behavior. This kind of rectifying paves a new way for resolving the sneak current issue in RRAM arrays.
