More Information
Summary:A storage device includes a non-volatile memory device including a first memory region and a second memory region, memory cells of the first memory region being at different levels from memory cells of the second memory region and a controller configured to control a base data protection operation against a rework for a reflow process by including a first operation of migrating base data stored in the first memory region to the second memory region before the rework for a first reflow process and a second operation of restoring the base data from the second memory region to the first memory region after completing the rework for the reflow process. The controller is configured to provide, to a host, management information including at least one of first information on a current state in a base data protection operation against the rework, second information on the first memory region, and third information on the second memory region.
