    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.

    Abstract: A semiconductor memory device includes a word line extending in a vertical direction, a semiconductor pattern having a ring-shaped horizontal cross-section that extends around the word line, a bit line at a first end of the semiconductor pattern, and a capacitor structure at second end of the semiconductor pattern. The capacitor structure includes a lower electrode layer electrically connected to the second end of the semiconductor pattern, having a ring-shaped horizontal cross-section, and including a connector extending in the vertical direction. A first segment extends in a horizontal direction from an upper end of the connector, and a second segment extends in the horizontal direction from a lower end of the connector. An upper electrode layer surrounded by the lower electrode layer, extends in the vertical direction, and a capacitor dielectric layer is between the lower electrode layer and the upper electrode layer.
