Abstract
In a system for programming non-volatile storage, technology is disclosed for programming with greater precision and reasonable program times. In one embodiment, a first voltage is applied to a bit line for a first non-volatile storage element in order to inhibit that first non-volatile storage element. A first program voltage is applied to the first non-volatile storage element. For example, a program pulse is applied to a control gate for the first non-volatile storage element. During the program pulse, the bit line is changed from said first voltage to a second voltage, where the second voltage allows the first non-volatile storage element to be programmed.
