Claim 12:
13. A method for programming a target memory cell of a memory array of a non-volatile memory system, comprising:
determining a total number of erase/programming (EP) cycles applied previously to the target memory cell;
based upon the determined total number of erase/programming (EP) cycles, determining a magnitude of a boosting voltage bias (VPASS) to be applied to an unselected word linei
wherein the magnitude of the boosting voltage bias (VPASS) is determined using a lookup table stored at the non-volatile memory system;
wherein the lookup table comprises a succession of different benchmark numbers of total erase/programming (EP) cycles;
wherein each benchmark number in turn corresponds to a magnitude of the boosting voltage bias (VPASS); and
wherein the magnitude of the boosting voltage bias (VPASS) corresponding to a specific benchmark number is equal to, or greater than, the magnitude of the boosting voltage bias (VPASS) corresponding to the benchmark number immediately prior to the specific benchmark number in the succession .
