    Abstract: A memory device includes a memory cell that is configured to have data stored therein, and a control logic that is configured to determine a dummy voltage based on a location of a selected word line electrically connected to the memory cell, and is configured to apply the dummy voltage to dummy word lines. First and second ones of the dummy word lines are adjacent to opposing ends in a vertical direction of a memory NAND string including the memory cell, respectively.

    Abstract: Disclosed is a flash memory including first to third memory cells connected to a cell string, a first selection line configured to select the cell string, a second selection line configured to select a connection with a common source line, a first word line connected to the first memory cell and positioned adjacent to the first or second selection line, a second word line connected to the second memory cell and adjacent to the first word line, and a third word line connected to the third memory cell and positioned between the second word line and the first or second selection line. Wherein during a read operation, a first recovery voltage is applied to unselected word lines when the selected word line is the second word line, and a second recovery voltage is applied to the unselected word lines when the selected word line is not the second word line.

    Abstract: An operating method of a nonvolatile memory device for programming multi-page data, the operating method including: receiving the multi-page data from a memory controller; programming first page data among the multi-page data to first memory cells connected to a word line adjacent to a selected word line; reading previous page data previously stored in second memory cells connected to the selected word line based on a first sensing value and a second sensing value after programming the first page data, calculating a first fail bit number by comparing first bits of the previous page data read based on the first sensing value to second bits of the previous page data read based on the second sensing value; and programming the previous page data read from the second memory cells and second page data among the multi-page data to the second memory cells based on the first fail bit number.

    Abstract: A nonvolatile memory includes a first sub-block defined by a first string select line and a first word line; a second sub-block defined by a second string select line different from the first string select line and a second word line different from the first word line; a first vacant block defined by the first string select line and the second word line; and a second vacant block defined by the second string select line and the first word line. First data is programmed in the first sub-block with, second data is programmed in the second sub-block, and no data is programmed in the first vacant block and the second vacant block.
