Abstract
An erasing method used in a flash memory having memory blocks is illustrated, each of the memory blocks is divided into a plurality of memory sectors, and steps of the erasing method is illustrated as follows. An erasing and verifying process is performed sequentially on the memory blocks or the memory sectors of the memory block according to a memory sector enable signal. An over-erased correcting and verifying process is performed sequentially on the memory blocks or the memory sectors of the memory block according to the memory sector enable signal, wherein the memory sector enable signal is set to be asserted if an over-erased correction is performed on at least one of the memory blocks or at least one of the memory sectors of the memory block.
