Abstract

A semiconductor device includes a first electrode, a ferroelectric layer disposed on the first electrode, a dielectric layer disposed on the ferroelectric layer, charge trap sites disposed in an inner region of the dielectric layer, and a second electrode disposed on the dielectric layer. The dielectric layer may have a non-ferroelectric property. The dielectric layer and the ferroelectric layer are disposed between the first electrode and the second electrode and connected in series to each other. The semiconductor device may include charge trap sites distributed in an inner region of the dielectric layer having a non-ferroelectric property.
