2- - 2-Terminal Switching Device Having Bipolar Switching Property and Resistance Memory Cross-Point Array Having the Same

摘要

A two-terminal switching device having bidirectional switching characteristics and a resistive memory device cross-point array including the same are provided. The two-terminal switching element includes a first electrode and a second electrode. A pair of first conductivity type metal oxide semiconductor layers electrically connected to the first electrode and the second electrode are disposed. A second conductive metal oxide semiconductor layer is disposed between the first conductive metal oxide semiconductor layers.
