Abstract

The invention provides a graded porous oxide memristor shaped like a melting hole, and the basic structure of the memristor sequentially comprises a bottom electrode layer, oxide layers and a top electrode layer from bottom to top. The memristor is characterized in that the oxide layers serve as resistive function layers and comprise a first oxide layer and a second oxide layer, and the second oxide layer is close to one side of the bottom electrode layer; the second oxide layer is of a porous structure and is of a similar-melting-hole graded porous structure, wherein the porous channels of the porous structure are communicated with one another, and the transportation of metal ions can be regulated and controlled under the action of an electric field; when the external electric field is removed, metal ions can be stored. The oxide memristor has stable, multi-resistance-state and low-energy-consumption memristor characteristics, a new path is provided for exploration of a memristor mechanism, and the electrical performance of the memristor can be improved; the memristor has good characteristics in the aspect of artificial synapse simulation, and a great application prospect is provided for neuromorphic calculation.
