  • Publication number: 20210166766
    Abstract: A memory device includes a plurality of memory cells. Each row of the plurality of memory cells is coupled to a respective one of a plurality of wordlines. A method of programming the memory device includes applying a program voltage to a selected wordline of the plurality of wordlines. The method also includes applying a series of incremental verifying voltages to the selected wordline in a first time period after applying the program voltage. The method further includes floating an unselected wordline of the plurality of wordlines in a second time period at least partially overlapping the first time period. The unselected wordline is adjacent to the selected wordline.

  • Patent number: 10943663
    Abstract: A method of programming a flash memory device includes selecting a first wordline of a plurality of wordlines to select a selected wordline, the selected wordline corresponding to a target memory cell and performing a programming loop. The programming loop includes applying a program voltage to the selected wordline and performing a verification to the target memory cell. The verification includes applying a pre-pulse voltage to the selected wordline, applying a plurality of pass voltages to unselected wordlines of the plurality of wordlines, after applying the pre-pulse voltage, applying a series of incremental verifying voltages to the selected wordline, and after applying the pre-pulse voltage, applying a floating voltage to a second wordline of the plurality of wordlines. The second wordline being adjacent to the selected wordline is programmed after the selected wordline.
