Abstract

Disclosed is a semiconductor memory device including a substrate, a plurality of source lines extending in a first direction on the substrate, a plurality of word lines crossing the source lines and extending in a second direction different from the first direction, a plurality of bit lines crossing the source lines and the word lines and extending in a third direction different from the first direction and the second direction, and a plurality of memory cells disposed at intersections between the source lines, the word lines, and the bit lines. The first, second, and third directions are parallel to a top surface of the substrate.
