Abstract
A non-volatile memory device includes a first memory cell array, a first error correction code (ECC) decoder and a controller. The first memory cell array is divided into a first sub-array and a second sub-array by a first address boundary. The first ECC decoder is coupled to the first memory cell array, performs an ECC operation on read-out data from first memory cell array. The controller is coupled to the first memory cell array and the first ECC decoder, adjusts the first address boundary according to a first ECC failure bit number.
