摘要
The embodiment of the present invention in the buffer cache of equipment includes a central processing unit and a buffer cache device; for providing a disk buffering between storage, non-volatile memory device deulrosseo is newest to be made dirty in terms of realizing a cache block and writes the administrative unit combined may include for keeping magazine about cache block protection (icing) in this cache block (dirty modern state). Particularly; during normal operation; dirty (freezing to make dirty) is set in write-protect; but it operative so that the buffered inspection station of the content to the data block of insoluble cache block; according to an abnormal end of system, with reference to journal management, by updating, be set among the cache block of the dirty state of cache block write-protect in storage can be with recovery system.
