The present invention relates to an apparatus and method for indicating flash memory life. While data is being stored in a flash memory, the number of writes in a plurality of blocks of the flash memory increases. The amount of flash memory life is calculated on the basis of the number of write times in the plurality of blocks. The calculated amount of life can be transmitted to a host. In addition, when the calculated amount of life is greater than a threshold value, a signal providing notice that the life of the flash memory has reached a dangerous level can be output.

The present invention relates to a grouping method and device for enhancing redundancy removing performance for a storage unit such as a hard disk, a solid state disk (SSD), etc. The grouping method for enhancing performance of a redundancy removing technology may include: extracting samples from data that is stored in a buffer of a memory and is standing by to be processed; performing remaining calculations on the extracted samples; and grouping samples by connecting them to a bucket corresponding to a resultant value of the remaining calculations.

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.

The present invention relates to a method and device for storing data in a flash memory using address mapping for supporting various block sizes. A storage device determines the size of a block that a host system uses on the basis of the size of data that the host system requests and uses the determined block size as a mapping unit. Additionally, the storage device divides a logical address space into at least one area, and maps an address using the minimum units of different mappings in each divided area.
