Abstract
A method and system for cache management in a storage device is disclosed. A portion of unused memory in the storage device is used for temporary data cache so that two levels of cache may be used (such as a permanent data cache and a temporary data cache). The storage device may manage the temporary data cache in order to maintain clean entries in the temporary data cache. In this way, the storage area associated with the temporary data cache may be immediately reclaimed and retasked for a different purpose without the need for extraneous copy operations.
