Abstract
Disclosed are a memory device, including: a memory block including a plurality of cell strings; a peripheral circuit configured to set voltages for a program operation of selected memory cells in the cell strings, and program the selected memory cells by using the set voltages; and a control circuit configured to control the peripheral circuit so that the selected memory cells are programmed in response to a program command, and increase a channel voltage of non-selected cell strings including non-selected memory cells while the selected memory cells are programmed, and an operating method thereof.
Claims12
An operating method of a memory device, comprising:
- determining whether a current program operation condition is equal to or higher than a pre-set program operation condition when a program operation of a selected memory cell included in a selected cell string is performed;
- increasing a channel voltage of a non-selected cell string when the program operation condition is equal to or higher than the pre-set program operation condition;
- and
- programming the selected memory cell of the selected cell string.
An operating method of a memory device, comprising:
- identifying a program operation condition of a selected memory cell of a selected memory string in which a target voltage is greater than a reference value when a program operation is performed;
- increasing a source line voltage when the program operation condition is identified;
- and
- programming the selected memory cell of the selected memory string.
An operating method of a memory device, comprising:
- identifying a program operation condition of a selected memory cell of a selected memory string in which a target voltage is greater than a reference value when a program operation is performed;
- increasing a source select line voltage of a non-selected cell string when the program operation condition is identified;
- and
- programming the selected memory cell of the selected memory string.
