  • 1 T flash memory recovery scheme for over-erasure
    Patent number: 6711065
    Abstract: Flash EEPROM cells are erased and recovered to a common threshold voltage by a two step process. First, the cells are erased. Second, the fixed (control) gates are set at a voltage of the same polarity as the programming voltage and at a magnitude of about half the programming voltage. The source is allowed to float and the drain (bitline) and body are set at a low level and at a polarity opposite to the programming voltage polarity.
