Abstract
A self-selecting memory device includes a first conductive line on a substrate, a first memory cell on the first conductive line, a second conductive line on the first memory cell, a second memory cell on the second conductive line, and a third conductive line on the second memory cell. The first memory cell includes a first electrode, a first switching memory unit and a second electrode sequentially and vertically stacked. The second memory cell includes a third electrode, a second switching memory unit and a fourth electrode sequentially and vertically stacked. The first switching memory unit includes a first SSM pattern contacting an upper surface of the first electrode and including an OTS material, and a first nitrogen-containing pattern contacting an upper surface of the first SSM pattern and a lower surface of the second electrode and including an OTS material doped with nitrogen.
