  • Erase and Program Method of Flash Memory Device for Increasing Program Speed of Flash Memory Device
    Publication number: 20070058446
    Abstract: The present invention relates to erase and program methods of a flash memory device including MLCs for increasing the program speed. In the erase method according to the present invention, MLCs are pre-programmed so that a voltage range in which threshold voltages of MLCs are distributed can be reduced. Therefore, a fail occurrence ratio can be reduced when erasing MLCs, the threshold voltage distribution of MLCs can be improved and an overall program time can be shortened in a subsequent program operation.
