摘要：
A method, implemented by at least an error correction code (ECC) decoder and a controller, estimates and corrects errors in memory cells. The method includes identifying a first candidate group of memory cells having an error-generation possibility using a first method for error estimation; identifying a second candidate group of memory cells having an error-generation possibility using a second method for error estimation; and correcting errors in at least one cell commonly included in the first and second candidate groups.
