Abstract
A method for determining a storing state of a flash memory is provided. The method includes the following steps. Firstly, plural first specific cell patterns are programmed into the flash memory. Then, plural second specific cell patterns are programmed into the flash memory. Then, a slicing voltage is adjusted to allow a distinguishable error percentage to be lower than a predetermined value. Afterwards, a first storing state and a second storing state of other cells of the flash memory are distinguished from each other according to the adjusted slicing voltage.
