Abstract
A controller for controlling an access of a non-volatile memory having an error-correcting code area and a data area is provided. The controller includes an error-correcting module and a first inverting circuit electrically connected to the error-correcting module for inverting data and error-correcting codes corresponding to the data. When the controller both writes all 0xFF data in the data area and writes all 0xFF error-correcting codes in the error-correcting code area, the first inverting circuit inverts the all 0xFF data and the all 0xFF error-correcting codes into all 0x00 data and all 0x00 error-correcting codes, respectively.
