Abstract
A flash memory circuit has a flash memory array and a processor. The flash memory array has a plurality of erasable flash memory cells. Each of the flash memory cells is electrically connected to a corresponding bitline. If any over-erased flash memory cell exists in the flash memory array, a processor controls the flash memory circuit to apply a correction voltage to the bitline connected to the over-erased flash memory cell so as to correct the over-erased flash memory cell. The correction voltage is continuously applied until a current along the corresponding bitline drops below a predetermined value.
