Abstract: A semiconductor memory device includes: a first word line extending in a vertical direction; a second word line spaced apart from the first word line in a first horizontal direction and extending in the vertical direction; a first semiconductor pattern of a ring-shaped horizontal cross-section surrounding the first word line and constituting a portion of a first cell transistor; a second semiconductor pattern of a ring-shaped horizontal cross-section surrounding the second word line and constituting a portion of a second cell transistor; a cell capacitor between the first semiconductor pattern and the second semiconductor pattern and including a first electrode, a second electrode, and a capacitor dielectric film; a first bit line opposite the cell capacitor with respect to the first semiconductor pattern and extending in a second horizontal direction; and a second bit line opposite the cell capacitor with respect to the second semiconductor pattern.

Abstract: A semiconductor device includes a first conductive line and a second conductive line spaced apart from the first conductive line. A semiconductor pattern is disposed between the first conductive line and the second conductive line. The semiconductor pattern includes a first semiconductor pattern having first-conductivity-type impurities disposed adjacent to the first conductive line. A second semiconductor pattern having second-conductivity-type impurities is disposed adjacent to the second conductive line. A third semiconductor pattern is disposed between the first semiconductor pattern and the second semiconductor pattern. The third semiconductor pattern includes a first region disposed adjacent to the first semiconductor pattern and a second region disposed between the first region and the second semiconductor pattern. At least one of the first region and the second region comprises an intrinsic semiconductor layer. A first gate line crosses the first region and a second gate line crosses the second region.
