Abstract
A data storage device includes a flash memory and a controller. The flash memory includes a plurality of planes, and each of the planes includes a plurality of blocks. Each of the blocks includes a plurality of pages. The size of each page is N K-bytes, wherein N is a positive integer greater than 1. The controller is coupled to the flash memory to calculate the ECC bit number of each page using a detection unit of 1 Kbyte. The controller statistically calculates the number of detection units of the pages corresponding to different values of the ECC bit number in order to determine whether each plane of the flash memory is normal or not.
