Abstract
Provided is an electronic device including a semiconductor memory. The semiconductor memory may include: a substrate; a plurality of variable resistance elements formed over the substrate and arranged as a matrix, spacer patterns formed over the substrate to surround the variable resistance elements in the matrix with a thickness sufficient to define contact holes between the variable resistance elements, and a source line contact buried in the contact hole.
