Abstract
An electronic device includes a semiconductor memory including material layers each including one or more low-resistance areas and one or more high-resistance areas, insulating layers stacked alternately with the material layers and including protrusions extending more than the material layers, conductive pillars passing through the insulating layers and the low-resistance areas, conductive layers located between the protrusions, and variable resistance layers interposed between the low-resistance areas and the conductive layers.
