Abstract
An electronic device may include a semiconductor memory. The semiconductor memory may include: row lines; column lines intersecting the row lines; memory cells located in intersection regions of the row lines and the column lines, the memory cells including upper and lower electrodes; and interface layers located between the lower electrodes of the memory cells and the row lines, the interface layers having a width narrower than that of the row lines.
