Abstract
The inventive concepts provide a semiconductor memory device including variable resistance memory elements. The semiconductor memory device may include a first bit line disposed at a first height from a semiconductor substrate, a second bit line disposed at a second height, which is different from the first height, from the semiconductor substrate, a first variable resistance memory element connected to the first bit line, and a second variable resistance memory element connected to the second bit line. The first and second variable resistance memory elements may be disposed at substantially the same height from the semiconductor substrate.
