Abstract
A memory cell undergoing programming is determined as belonging to a particular one of a plurality of second threshold voltage ranges that divide a present threshold voltage range of the particular memory cell. Programming pulses are applied to program the particular memory cell to within the target threshold voltage range. At least one of a program voltage and a total duration of the programming pulses applied to the particular memory cell is varied, depending on the particular second threshold voltage range of the memory cell.
