Abstract
A high-performance write operation to program data to a group of non-volatile memory cells may be completed in response to applying a single programming pulse to the group. Programming of the cells may be verified (and/or corrected) after completion of the command. Verifying programming of the cells may comprise identifying under-programmed cells, and applying an additional programming pulse to the identified cells. The under-programmed cells may comprise cells within an under-program range below a target level. The under-program range may be determined based on a threshold voltage distribution of the cells in response to applying the single programming pulse.
