    • 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.
    • 非易失性存储器件包括在衬底上的一串非易失性存储器单元。 这一串非易失性存储单元包括衬底上的非易失性存储单元的第一垂直堆叠和非易失性存储单元的第一垂直堆叠上的串选择晶体管。 第二垂直堆叠的非易失性存储单元也设置在衬底上,并且在非易失性存储单元的第二垂直堆叠上提供接地选择晶体管。 非易失性存储单元的第二垂直堆叠被提供为与非易失性存储单元的第一垂直堆叠相邻。 在衬底中提供连接掺杂半导体区域。 该连接掺杂区域将非易失性存储器单元的第一垂直堆叠与第二垂直堆叠的非易失性存储器单元电连接,使得这些堆叠可以作为单个NAND型存储器单元串工作。
