In a non-volatile memory a group of memory cells is programmed respectively to their target states in parallel using a multiple-pass index programming method which reduces the number of verify steps. For each cell a program index is maintained storing the last programming voltage applied to the cell. Each cell is indexed during a first programming pass with the application of a series of incrementing programming pulses. The first programming pass is followed by verification and one or more subsequent programming passes to trim any short-falls to the respective target states. If a cell fails to verify to its target state, its program index is incremented and allows the cell to be programmed by the next pulse from the last received pulse. The verify and programming pass are repeated until all the cells in the group are verified to their respective target states. No verify operations between pulses are necessary.

A different pass voltage is used in different programming passes on an adjacent word line of a selected word line which is being verified. In particular, a lower pass voltage can be used in a first pass than in a second pass. The programming process may involve a word line look ahead or zigzag sequence in which WLn is programmed in a first pass, followed by WLn+1 in a first pass, followed by WLn in a second pass, followed by WLn+1 in a second pass. An initial programming pass may be performed before the first pass in which storage elements are programmed to an intermediate state and / or to a highest state.
