    摘要: Disclosed is a bad block management method of a memory system that includes virtual blocks having a plurality of units and at least one reserved block. The bad block management method includes mapping the virtual blocks and the at least one reserved block onto one physical block in the plurality of physical blocks, determining that a first virtual block in the virtual blocks includes a bad virtual block unit, and replacing the bad virtual block unit in the first virtual block with a first reserved block unit selected from the reserved block units.

    摘要: An approach is provided for improving write performance using a buffer cache based on a buffer replacement policy. A buffer cache manager is configured to improve address mapping scheme associated with write performance between an application system and a storage device system. The manager selects a victim page to be evicted from a victim block of a buffer cache according to a recently-evicted-first rule. And the victim block is selected associated with a log block of a memory.

    摘要: Disclosed is a memory system including a storage device such a hard disk or flash memory, and an access method. The memory system includes: a storage device storing metadata; a file system generating and managing abstract data associated with the metadata; and a cache memory temporarily storing the abstract data. The file system accesses the metadata of the storage device with reference to the abstract data stored in the cache memory.
