Abstract

A memory device including a dielectric thin film having a plurality of dielectric layers and a method of manufacturing the same are provided. The memory device includes: a bottom electrode; at least one dielectric thin film disposed on the bottom electrode and having a plurality of dielectric layers with different charge trap densities from each other; and an top electrode disposed on the dielectric thin film. Therefore, a memory device, which can be readily manufactured by a simple process and can be highly integrated using its simple structure, can be provided.
