Abstract:
1. A method for programming a plurality of memory cells along a word line to a respective programmed state, the method comprising: programming each memory cell of the plurality memory cells along the word line to within a predetermined range of its respective programmed state by biasing each of the plurality of memory cells along the word line with at least an initial first programming voltage of a plurality of first programming voltages; reading threshold voltages of memory cells adjacent to the plurality memory cells along the word line to determine an effect of at least the initial first programming voltage of the plurality of first programming voltages on the threshold voltages of the memory cells adjacent to the plurality memory cells along the word line, wherein programming of the memory cells adjacent to the plurality memory cells along the word line is based on the determined effect of at least the initial first programming voltage of the plurality of first programming voltages on the threshold voltages of the memory cells adjacent to the plurality memory cells along the word line; and after programming each memory cell of the plurality memory cells along the word line to within the predetermined range of its respective programmed state, programming each of the plurality of memory cells along the word line to its respective programmed state by biasing each of the plurality of memory cells along the word line with at least an initial second programming voltage of a plurality of second programming voltages, wherein the initial second programming voltage is less than the initial first programming voltage.
