    摘要: Nonvolatile memory devices include a string of nonvolatile memory cells on a substrate. This string of nonvolatile memory cells includes a first vertical stack of nonvolatile memory cells on the substrate and a string selection transistor on the first vertical stack of nonvolatile memory cells. A second vertical stack of nonvolatile memory cells is also provided on the substrate and a ground selection transistor is provided on the second vertical stack of nonvolatile memory cells. This second vertical stack of nonvolatile memory cells is provided adjacent the first vertical stack of nonvolatile memory cells. A conjunction doped semiconductor region is provided in the substrate. This conjunction doped region electrically connects the first vertical stack of nonvolatile memory cells in series with the second vertical stack of nonvolatile memory cells so that these stacks can operate as a single NAND-type string of memory cells.

    摘要: A charge trap nonvolatile memory device includes a gate electrode on a substrate; a charge trapping layer between the substrate and the gate electrode; a charge tunneling layer between the charge trapping layer and the substrate; and a charge blocking layer between the gate electrode and the charge trapping layer. The charge trapping layer includes a first charge trapping layer having a first energy band gap and a second charge trapping layer having a second energy band gap that is different than the first energy band gap. The first and second charge trapping layers are repeatedly stacked and the first and second energy band gaps are smaller than energy band gaps of the charge tunneling layer and the charge blocking layer.
