Abstract
A memory device includes a plurality of first conductive lines on a substrate and extending in a first direction, a plurality of second conductive lines on the plurality of first conductive lines and extending in a second direction intersecting the first direction, and a plurality of memory cells respectively between the plurality of first conductive lines and the plurality of second conductive lines. Each of the plurality of memory cells includes a switching element and a variable resistance material layer. The switching element includes a material having a composition of [GePSe][O], where 0.15≤X≤0.50, 0.15≤Y≤0.50, 0.35≤Z≤0.70, and 0.01≤W≤0.10.
