Abstract
An electronic device includes a semiconductor memory that includes: first and second lines spaced apart from each other and crossing each other; a third line spaced apart from the second line and crossing the second line; a first variable resistance element interposed between the first and second lines and overlapping an intersection of the first and second lines; a second variable resistance element interposed between the second and third lines and overlapping an intersection of the second and third lines, a part of the second variable resistance element generating a greater amount of heat than a part of the first variable resistance element when a current flows through the first variable resistance element in an opposite direction to a current flowing through the second variable resistance element; and a material layer serially connected with the second variable resistance element, disposed between the second and third lines, and exhibiting electrical resistance.
