Abstract
A bitline current generator, for a non-volatile memory array which comprises a plurality of memory bitcells and bitlines, comprises a switching means for each bitline for coupling a bitline to a program voltage supply when the bitline is selected for programming and a variable current source for providing a programming current to said selected bitlines. The variable current source is adapted to select a level of said programming current such that the programming of the selected memory bitcells does not disturb the programed state of the unselected memory bitcells on unselected bitlines.
