Abstract

See full text

A variable resistance non-volatile memory device can include a semiconductor substrate and a plurality of first conductive lines each extending in a first direction perpendicular to the semiconductor substrate and spaced apart in a second direction on the semiconductor substrate. A second conductive line can extend in the second direction parallel to the semiconductor substrate on a first side of the plurality of first conductive lines and a third conductive line can extend in the second direction parallel to the semiconductor substrate on a second side of the plurality of first conductive lines opposite the first side of the plurality of first conductive lines. A plurality of first non-volatile memory cells can be on the first side of the plurality of first conductive lines and each can be coupled to the second conductive line and to a respective one of the plurality of first conductive lines, where each of the plurality of first non-volatile memory cells can include a switching element, a variable resistance element, and an electrode arranged in a first sequence. A plurality of second non-volatile memory cells can be on the second side of the plurality of first conductive lines and each can be coupled to the third conductive line and to a respective one of the plurality of first conductive lines, wherein each of the plurality of second non-volatile memory cells includes a switching element, a variable resistance element, and an electrode that are arranged in a second sequence, wherein the first sequence and the second sequence are symmetrical with one another about the plurality of first conductive lines.
