Abstract
Non-volatile memory devices include memory cells therein with reduced cell-to-cell coupling capacitance. These memory cells include floating gate electrodes with open-ended wraparound shapes that operate to reduce the cell-to-cell coupling capacitance in a bit line direction, while still maintaining a high coupling ratio between control and floating gate electrodes within each memory cell.
