Abstract: A method for program verify is disclosed, such as one in which a threshold voltage of a memory cell that has been biased with a programming voltage can be determined and its relationship with multiple program verify voltage ranges can be determined. The program verify voltage range in which the threshold voltage is located determines the subsequent bit line voltage. The subsequent bit line voltage may be less than a previous bit line voltage used to program the memory cell.

Abstract: Memory devices and methods for operating a memory cell are disclosed, such as a method that uses two program verify levels (e.g., low program verify level and program verify level) to determine how a data line voltage should be increased. A threshold voltage of a memory cell that has been biased with a programming voltage is determined and its relationship with the two program verify levels is determined. If the threshold voltage is less than the low program verify level, the data line can be biased at a ground voltage (e.g., 0V) for a subsequent programming pulse. If the threshold voltage is greater than the program verify level, the data line can be biased at an inhibit voltage for a subsequent programming pulse. If the threshold voltage is between the two program verify levels, the data line voltage can be increased for each subsequent programming pulse in which the threshold voltage is between the two program verify levels.
