Method for operating storage controller and method for operating storage device including the same wherein garbage collection is performed responsive to free block unavailable during reuse
A method of operating a storage controller, for controlling a garbage collection operation so that blocks included in a non-volatile memory satisfy reuse constraints, includes determining whether the number of free blocks among the blocks is smaller than a first reference value for triggering a garbage collection operation and performing the garbage collection operation on the blocks until the number of free blocks is equal to a second reference value larger than the first reference value according to a result of the determination.
