摘要:
Methods and devices for operating non-volatile storage are disclosed. One or more programming conditions depend on the location of the word line that is selected for programming, which may reduce or eliminate program disturb. The voltage applied to the gate of a select transistor of a NAND string may depend on the location of the selected word line. This could be either a source side or drain side select transistor. This may prevent or reduce program disturb that could result due to DIBL. This may also prevent or reduce program disturb that could result due to GIDL. A negative bias may be applied to the gate of a source side select transistor when programming at least some of the word lines. In one embodiment, progressively lower voltages are used for the gate of the drain side select transistor when programming progressively higher word lines.

Methods and devices for operating non-volatile storage are disclosed. One or more programming conditions depend on the location of the word line that is selected for programming. Applying a selected word line dependent program condition may reduce or eliminate program disturb. The voltage applied to a common source line may depend on the location of the word line that is selected for programming. This may prevent or reduce punch-through conduction, which may prevent or reduce program disturb. The voltage applied to bit lines of unselected NAND strings may depend on the location of the word line that is selected for programming. This may prevent or reduce punch-through conduction.
