Abstract
The present disclosure provides a self-rectifying RRAM cell structure including a first electrode layer formed of a nitride of a first metal element, a second electrode layer formed of a second metal element that is different from the first metal element, a first resistive switching layer and a second resistive switching layer. The first resistive switching layer is sandwiched between the first electrode layer and the second resistive switching layer, and the second resistive switching layer is sandwiched between the first resistive switching layer and the second electrode layer. The first resistive switching layer has a first bandgap that is lower than the second bandgap of the second resistive switching layer. Furthermore, a RRAM 3D crossbar array architecture is also provided.
