Abstract: An operating method of a storage device includes reading a wear-out pattern of a memory block when a controller determines the memory block is a re-use memory block of a non-volatile memory device; selecting an operation mode corresponding to the read wear-out pattern using the controller; and transmitting the selected operation mode to the non-volatile memory device using the controller.
