Abstract: A storage device includes a non-volatile memory device including a plurality of memory blocks; and a memory controller configured to control a garbage collection operation of copying valid data of a source block among the plurality of memory blocks to a destination block. The memory controller is configured to read a logical address stored in a page included in the source block, determine a validity of user data stored in the page included in the source block based on the logical address, read the valid data, which includes the user data determined to be valid, from the non-volatile memory device, and perform a write operation on the destination block by transferring the read valid data to the non-volatile memory device.
