An experimental confirmation of automatic threshold voltage convergence in a flash memory using alternating word-line voltage pulses
H. Gotou · IEEE Electron Device Letters · 1997
A flash memory using the alternating word-line voltage pulses is experimentally studied. Relations between pulse count and the threshold voltages of the cell are obtained. An automatic threshold voltage convergence was confirmed by the relation, and the threshold voltage is successfully controlled by the word-line pulse voltage. An application to a multi-level flash memory is proposed.
