INTERFACE MANAGEMENT METHOD AND METHOD FOR PROCESSING MAPPING IN STORAGE DEVICE USING THE SAME

摘要

PURPOSE: An interface management method and a mapping process method of a storage device using the same are provided to optimize mapping by classifying a plurality of data groups according to the attribute of data pages. CONSTITUTION: A host device classifies data pages stored in a storage device into a plurality of data groups according to the attribute of the data pages(S101). The host device classifies the data pages into the plurality of the data groups according to the occurrence frequency of update and file attributes. The file attribute is determined based on a kind of the files or the extension information of the files. The host device transmits setting information for a data group to a storage device(S102). The setting information for the data group is transmitted with an initially defined command code.
