Abstract
An electronic device may include a semiconductor memory. The semiconductor memory may include a trench formed in a substrate; a gate dielectric layer formed on a surface of the trench; a gate electrode which is formed on the gate dielectric layer, gap-fills a part of the trench, and contains dopants; a diffusion region which is formed to be in contact with the surface of the trench and to correspond to the gate electrode in the substrate; junction regions formed in the substrate at both sides of the trench; and a memory element coupled to a junction region in a side of the trench.
