Abstract

A semiconductor memory device includes: an active layer spaced apart from a substrate wherein the active layer extends in a direction parallel to the substrate, and includes a channel; a bit line extending in a direction perpendicular to the substrate and coupled to a first end of the active layer; a capacitor coupled to a second end of the active layer; and a double word line including a pair of dual work function electrodes that extend in a direction crossing the active layer with the active layer interposed therebetween, wherein each of the dual work function electrodes includes: a high work function electrode which is adjacent to the bit line; and a low work function electrode which is adjacent to the capacitor and having a lower work function than the high work function electrode.
