Abstract: In a programming operation that includes repeated bitscan, program, and verify steps, the bitscan steps may be hidden by performing bitscan in parallel with program preparation and program steps. The effect of a program step may be predicted from previous observation so that when a bitscan indicates that the memory cells are close to being programmed, a last programming step may be completed without subsequent verification or bitscan steps.
