Abstract:
The programming techniques include the step of providing a memory device that includes a plurality of memory cells that are divided into at least two groups including a first group and a second group. The first group includes memory cells that are coupled to full select gate drains (SGDs), and the second group includes memory cells that are coupled to partial SGDs. The method continues with the step of applying a programming voltage to a selected word line that includes at least one memory cell of the first group and at least one memory cell of the second group. Simultaneous to the application of the programming voltage, the method continues with applying voltages to bit lines coupled to memory cells. The voltages being determined based on if the memory cells are of the first group or are of the second group.
