Abstract
An electronic device may include a semiconductor memory. The semiconductor memory may include a stack in which a plurality of dielectric layers and a plurality of first electrodes are alternately stacked over a substrate in a vertical direction relative to the substrate; a hole pattern passing through the stack in the vertical direction and having a polygonal shape when viewed in a plan view; a plurality of second electrodes disposed on respective sidewalls of the hole pattern; and a plurality of variable resistance layers interposed between the plurality of second electrodes and the plurality of horizontal electrodes.
