Abstract
A non-volatile memory device may include a memory cell array, a peripheral circuit and a control logic. The memory cell array may include pages including data cells and over-program flag cells configured to represent whether or not the data cells may correspond to an over-programmed cells. The peripheral circuit may be configured to store data in the memory cell array or read the data from the memory cell array. The control logic may be configured to determine whether or not the data cells are programmable when a program command may be received from an external device. The control logic may be configured to program the over-program flag cell corresponding to the data cells when the data cells are not programmable.
Claims19
A non-volatile memory device comprising:
- a memory cell array including word lines, the word lines including data cells and an over-program flag cell configured to represent whether or not the data cells correspond to an over-programmed cells;
- a peripheral circuit configured to store data in the memory cell array or read data from the memory cell array;
- and
- a control logic for controlling the peripheral circuit to determine whether or not the data cells are programmable and to program the over-program flag cell corresponding to the data cells under a condition that the data cells are not programmable, when the control logic receives a program command from an external device.
A method for operating a non-volatile memory device, the method comprising:
- determining whether or not data cells are programmable when a program command is received from an external device;
- and
- programming an over-program flag cell corresponding to the data cells when the data cells are not programmable.
A data storage device comprising:
- a non-volatile memory device;
- and
- a controller configured to the non-volatile memory device,
- wherein the non-volatile memory device comprises:
- a memory cell array including word lines, the word lines including data cells and an over-program flag cell configured to represent whether or not the data cells correspond to an over-programmed cells;
- a peripheral circuit configured to store data in the memory cell array or read data from the memory cell array;
- and
- a control logic for controlling the peripheral circuit to determine whether or not the data cells are programmable and to program the over-program flag cell corresponding to the data cells under a condition that the data cells are not programmable, when the control logic receives a program command from the controller.
