Abstract
Methods and devices for operating non-volatile storage are disclosed. One or more programming conditions depend on the word line that is selected for programming. Applying a selected word line dependent program condition may reduce or eliminate program disturb. The duration of a programming pulse may depend on the word line that is selected for programming. This could be a physical characteristic of the word line or its location on a NAND string. As one example, a shorter pulse width may be used for the programming signal when programming edge word lines.
