A program operation in a non-volatile memory is segmented at predefined junctures into smaller segments for execution over different times. The predefined junctures are such that they allow unambiguous identification when restarting the operation in a next segment so that the operation can continue without having to restart from the very beginning of the operation. This is accomplished by requiring the programming sequence of each segment to be atomic, that is, to only terminate at a predetermined type of programming step. In a next segment, the terminating programming step is identified by detecting a predetermined pattern of ECC errors across a group of programmed wordlines.
