  • Method for operating a memory cell array
    Patent number: 7113428
    Abstract: Prior to the reprogramming of a selected flash memory cell of a memory cell array, electrons being removed from the memory layer (M) in the channel region (C) by Fowler-Nordheim tunneling, a lower potential for incipient programming of the memory cell is applied to the relevant word line (WLn) while the associated bit line (BLm) remains at the basic potential. What is thereby achieved is that a gate disturb occurring during the programming operation does not lead to erratic bits along the affected word line (WLn).
    Type: Grant
