  • Publication number: 20220366963
    Abstract: A flash memory storage apparatus includes a memory cell array and a voltage generating circuit. The memory cell array includes at least one memory cell string coupled between a bit line and a source line and including memory cells; each memory cell is coupled to a corresponding word line. The voltage generating circuit is coupled to the memory cell array and configured to output a bias voltage to the word line. A first voltage is applied to a selected word line. A second voltage and a third voltage are applied to unselected second and third word lines, respectively. The first voltage is greater than the second voltage, and the second voltage is greater than the third voltage. The second word line and the third word line are located on two sides of the first word line. A biasing method of a flash memory storage apparatus is also provided.
