Abstract
A memory controller includes a damaged-column manager, an error checking and correcting decoder (ECC decoder) and a damaged-column decision circuit. The damaged-column manager logs a damaged-column address information in the flash memory. The ECC decoder receives a read data read by the flash memory and generates an error information according to whether or not the read data has error. The damaged-column decision circuit receives the error-column address and counts the number of accumulated generated times corresponding to the error-column address. The damaged-column decision circuit updates the damaged-column address information according to an error information.
