Abstract: A refresh leveraging driving method is provided which includes deciding a unit of word lines to be driven at a refresh leveraging operation to be the same as a redundancy repair row unit setting a lower row address of an input refresh leveraging address corresponding to the decided refresh leveraging row driving unit to a don't care state; and internally generating the don't care lower row address of the refresh leveraging address to drive word lines according to a combined refresh leveraging address.
