Abstract
A semiconductor memory device includes bodies electrically floating; sources; drains; gate electrodes, each of which is adjacent to one side surface of the one of the bodies via a gate dielectric film; plates, each of which is adjacent to the other side surface of the one of the bodies via a plate dielectric film; first bit lines on the drains, the first bit lines including a semiconductor with a same conductivity type as that of the drains; and emitters on the semiconductor of the first bit lines, the emitters including a semiconductor with an opposite conductivity type to that of the semiconductor of the first bit lines, wherein the emitters are stacked above the bodies and the drains.
