Abstract
When it is determined that a first super memory block among a plurality of super memory blocks satisfies an exchange condition, the storage device may exchange a first memory unit in the first super memory block with a second memory unit included in a second super memory block among the plurality of super memory blocks. In this case, the first memory unit is a bad memory unit and the second memory unit is a normal memory unit.
