Abstract: A method of managing a bad storage region of a memory device may include detecting a bad page of a selected data block that has failed in one of a program operation, a read operation, and an erase operation on the memory device; and performing a mapping process so that the detected bad page is excluded from a storage region to which data is to be programmed, wherein remaining pages of the selected data block excluding the bad page are allowed to be used as a storage region in a garbage collection operation.
