PURPOSE: A memory system and an access method thereof are provided to increase integrity of the memory system by reducing the capacitance of a cache memory by storing only partial information of the directory entry. CONSTITUTION: A memory system includes a storage device(110), a file system(120), and a cache memory(130). The storage unit stores the meta data. The file system generates and manages the summary information of the meta data. The cache memory stores the summary information of the meta data temporarily. The filing system accesses the meta data stored in the storing device in the cache memory.
