  • Nonvolatile memory devices having vertically integrated nonvolatile memory cell sub-strings therein
    Patent number: 9000508
    Abstract: Nonvolatile memory devices according to embodiments of the invention include highly integrated vertical stacks of nonvolatile memory cells. These vertical stacks of memory cells can utilize dummy memory cells to compensate for process artifacts that would otherwise yield relatively poor functioning memory cell strings when relatively large numbers of memory cells are stacked vertically on a semiconductor substrate using a plurality of vertical sub-strings electrically connected in series.
