STORAGE DEVICE FOR MANAGING DATA BASED ON A SET OF SPATIAL LOCAL INFORMATION, AN ELECTRONIC DEVICE INCLUDING THE SAME, AND A DATA MANAGEMENT METHOD THEREOF

摘要

PURPOSE: A storage device, an electronic device including the same, and a data management method thereof are provided to generate and manage a section according to a set of spatial local information and request history information corresponding to an input/output request, thereby easily grasping a data property and an access pattern.;CONSTITUTION: A section management module (122) generates a section which indicates logic addresses corresponding to an input/output request. The section management module manages the section by using a set of section information. A buffer (124) stores the data of the section and the section information corresponding to the input/output request. The section information includes a set of spatial local information which indicates the logic addresses and a set of request history information with the number of writing/reading requests. A buffer management module (126) manages the data stored in the buffer. The buffer management module deletes the data of the section based on the section information.;COPYRIGHT KIPO 2013
