摘要： A memory system according to an embodiment of the present invention includes a volatile first storing unit, a nonvolatile second storing unit, a controller that transfers data between a host apparatus and the second storing unit via the first storing unit. The memory system monitors whether data written from the host apparatus in the first storing unit has a specific pattern in management units. When data to be flushed to the second storing unit has the specific pattern, the memory system set an invalid address value that is not in use in the second storing unit to the data.

摘要： According to one embodiment, a free blocks included in a nonvolatile semiconductor memory are classified into a plurality of free block management lists. When a free block is acquired at normal priority, the free block is acquired from the free block management list in which a number of free blocks is larger than a first threshold. When a free block is acquired at high priority, the free block is acquired from the free block management list irrespective of the first threshold.

摘要： A storage device for which restoration of data is possible without the need for excess equipment includes mirrored storage units for online use and for backup, and is capable of performing a data backup while continuing input and output of data. The storage device is further provided with an update data storage unit for storing update data. According to the storage device, even if the information stored in a storage unit for online use is not capable of being read because of a fault in the storage unit, it is possible to restore the data in the backup storage unit to the state that existed in the storage unit for online use immediately before the fault by applying the update data to the information stored in the storage device for backup.

摘要： A hierarchical memory scheme capable of improving a hit rate for the segment containing the random access point rather than improving the overall hit rate of the cache, and a data playback scheme capable of automatically detecting positions that are potentially used as playback start indexes by the user and attaching indexes, are disclosed. The hierarchical storage device stores random access point segment information from which a possibility for each segment to contain a point that can potentially be random accessed in future can be estimated, and controls a selection of the selected segments to be stored in the cache storage device according to the random access point segment information. The data playback device records a plurality of playback start indexes, each playback start index being information regarding a playback position that is determined according to the user input which is recorded when the user input is in a prescribed pattern, and presents the plurality of playback start indexes to a user so as to urge the user to select a desired playback position.

摘要： According to one embodiment, a memory system includes a data manager and a data restorer. The data manager multiplexes difference logs by a parallel writing operation and stores them in a second storage area, the difference logs being difference logs indicating difference information before and after update of a management table; and thereafter multiplexes predetermined data as finalizing logs and stores them in the second storage area. The data restorer determines a system status at startup of the memory system, by judging whether irregular power-off occurs or data destruction occurs in the second storage area, based on a data storage state of the difference logs and the finalizing logs stored in the second storage area.
