Abstract
The present invention relates to a storage device that uses a flash memory that performs power loss recovery, and to a method of power loss recovery by using the storage device using the flash memory. The storage device stores change information on metadata in physical pages in which one or more logical pages are compressed and stored. The change information on the metadata is information representing how the metadata is changed in association with data in the one or more logical pages. The storage device may synchronize the metadata in the flash memory and recover the metadata by applying the change information on the metadata to the synchronized metadata when a power supply is disrupted.
