Abstract
A pre-match method includes: receiving an initial address; gradually increasing a current address according to the initial address; adding an offset value to the current address for generating a match address; generating a hit parameter by comparing the match address with at least one defect address stored in the mapping table; generating a redundancy address corresponding to the match address; and setting a Y-direction address as either the redundancy address or the current address according to the hit parameter.
