Abstract: A device and a method for reducing an initialization time of a storage medium are provided to reduce the time needed for initializing the storage medium such as a memory card in a host by storing ID information of the storage medium previously connected to the host and using the stored storage medium ID information. An interface(110) connects with a storage medium, and an ID information storing part(130) stores ID information of the storage medium. A controller(140) initializes the storage medium connected to the interface by using the storage medium ID information stored in the storing part. An ID information extractor(120) extracts the ID information from the storage medium connected with the interface at first and stores the extracted storage medium ID information to the ID information storing part.

Abstract: A device and a method for managing a file system are provided to prevent performance degradation of the file system for sectors, which are not synchronized and are not continuous by unpredictable sudden power-off, by storing a log reflecting change of metadata in a non-volatile memory storage medium. A memory(120) stores data and first metadata for the data, and a non-volatile storage medium(130) stores second metadata changed according to change of the data when the data is changed. A controller(140) updates the first metadata by using the second metadata. The controller checks remaining capacity of the non-volatile storage medium and stores the second metadata to a storage medium(110) when the remaining capacity of the non-volatile storage medium is smaller than a reference level.
