Method for processing data stored in a memory device and a data storage device utilizing the same
A data storage device includes a memory device and a controller. The memory device includes multiple memory blocks. Each memory block includes multiple pages. The controller is coupled to the memory device and includes an ECC engine configured to check and correct errors that have occurred in data stored in the memory blocks. When a number of error bits in a page of one of the memory blocks exceeds a threshold, the controller is configured to add a block number of the memory block in a predetermined queue and when a garbage collection procedure has been triggered, the controller is configured to perform garbage collection on the memory block.
