Abstract
A semiconductor memory device includes first conductive lines extending in a first direction on a substrate, second conductive lines extending in a second direction over the first conductive line, the first and the second conductive lines crossing each other at cross points, a cell structure positioned at each of the cross points, each of the cell structures having a data storage element, a selection element to apply a cell selection signal to the data storage element and to change a data state of the data storage element, and an electrode element having at least an electrode with a contact area smaller than that of the selection element, and an insulation pattern insulating the first and the second conductive lines and the cell structures from one another.
