Abstract
The present invention provides a highly integrated memory cell and a semiconductor memory device including the same. According to the present invention, a semiconductor memory device comprises: a substrate; an active layer spaced apart from the substrate, extending in a direction parallel to the substrate, and including a thin-body channel; a bit line extending in a direction vertical to the substrate and connected to one side of the active layer; a capacitor connected to another side of the active layer; and a first word line and a second word line extending in a direction crossing the thin-body channel with the thin-body channel interposed therebetween, wherein a thickness of the thin-body channel is smaller than thicknesses of the first word line and the second word line.
