- Abstract
- To integrate bipolar resistive switching cells into crosspoint structures, we serially connect a threshold-switching (TS) Pt/NbO2/Pt device with a memory-switching (MS) Pt/Nb2O5/Pt device and observe the suppression of the undesired sneak current. A simpler Pt/Nb2O5/NbO2/Pt bilayer oxide device was designed; it simultaneously exhibits TS and MS. The unique device characteristics in the metal/oxide/metal structure can be directly integrated into a crosspoint memory array without the diode; this can significantly reduce the fabrication complexity.
