TWO-TERMINAL SWITCHING ELEMENT HAVING BIDIRECTIONAL SWITCHING CHARACTERISTIC, RESISTIVE MEMORY CROSS-POINT ARRAY INCLUDING SAME, AND METHOD FOR MANUFACTURING TWO-TERMINAL SWITCHING ELEMENT AND CROSS-POINT RESISTIVE MEMORY ARRAY

摘要

Provided are a two-terminal switching element having a bidirectional switching characteristic, a resistive memory cross-point array including the same, and methods for manufacturing the two-terminal switching element and the cross-point resistive memory array. The two-terminal switching element includes a first electrode and a second electrode. A pair of first conductive metal oxide semiconductor layers electrically connected to the first electrode and the second electrode, respectively, is provided. A second conductive metal oxide semiconductor layer is disposed between the first conductive metal oxide semiconductor layers. Therefore, the two-terminal switching element can show a symmetrical and bidirectional switching characteristic.
