Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A non-volatile storage system comprising:
a memory structure comprising a three-dimensional memory structure that comprises NAND strings having memory cells;
means for programming the memory cells in a normal mode in which a program voltage is applied to a selected word line and a boosting voltage is applied to an unselected word line adjacent to the selected word line for which memory cells are already programmed;
means for stressing the memory cells in which a program voltage is applied to the selected word line while a stress voltage having a magnitude lower than the boosting voltage is applied to the unselected word line adjacent to the selected word line for which memory cells are already programmed; and
means for retiring the memory cells responsive to the memory cells failing a stress test criterion after the stress voltage is applied.
