Abstract
A semiconductor memory device including first-first conductive lines on a substrate; second-first conductive lines on the first-first conductive lines; first contacts connected to the first-first conductive lines; and second contacts connected to the second-first conductive lines, wherein the first-first conductive lines protrude in a first direction beyond the second-first conductive lines; the first-first conductive lines include first regions having a first thickness, second regions having a second thickness, the second thickness being greater than the first thickness, and third regions having a third thickness, the third thickness being smaller than the first thickness and smaller than the second thickness, and the second regions of the first-first conductive lines are between the first regions of the first-first conductive lines and the third regions of the first-first conductive lines.
