Abstract
A programming method for programming stored bits in floating gates of a flash memory cell or selected flash memory cells of a flash memory array is utilized for applying SSI injection on said flash memory cell or said selected flash memory cells of a flash memory array is disclosed. Constant charges at the drain regions of said flash memory cell or said selected flash memory cells of the flash memory array is implemented with a capacitor and a related switch for suppressing variant injected-charges-related properties in applying the SSI injection. A constant biasing current, which may be implemented with a constant current source or a current mirror equipped with a constant current source, is applied on source regions of said flash memory cell or said selected flash memory cells of the flash memory array for enhancing the suppression of said variant biasing properties.
