ABSTRACT:
A method for accessing a Flash memory including a plurality of blocks includes: selectively programming a page in a first block of the blocks; when a status of the Flash memory is abnormal, determining whether a number of error bits is less than a predetermined value; and when the number of error bits is not less than the predetermined value, moving the first block. An associated memory device and a controller thereof are also provided, where the controller includes: a read only memory (ROM) arranged to store a program code; and a microprocessor arranged to execute the program code to control the access to the Flash memory. In addition, when the number of error bits is not less than the predetermined value, the controller that executes the program code by utilizing the microprocessor moves the first block.
