Abstract
A suitable erase verification (ERSV) method of a flash memory apparatus is provided, which is different from the conventional ERSV method. That is, by managing the ERSV operation on the flash memory after at least once of erase operation, a flash memory controller in the flash memory apparatus selectively assigns at least one of de-selected sectors instead of all of the de-selected sectors to perform the ERSV. Therefore, by managing the ERSV operation on the flash memory, the time for the ERSV operation thereon is reduced.
