Abstract
Provided are methods, devices, and/or the like for reducing the bit line interference when programming non-volatile memory. One method comprises providing a non-volatile memory device comprising a set of cells, each cell associated with a bit line; shooting a programming voltage across each cell; detecting a threshold voltage for each cell; identifying a fast subset of the set of cells and a slow subset of the set of cells based at least in part on the detected threshold voltage for each cell; and shooting the programming voltage until the threshold voltage for each cell is greater than a verify voltage. For each shot a fast bit line bias is applied to the bit line associated each cell of the fast subset and a slow bit line bias is applied to the bit line associated with each cell of the slow subset.
