摘要： A memory system includes a first storing area included in a volatile semiconductor memory, a second and a third storing area included in a nonvolatile semiconductor memory, a controller that allocates the storage area of the nonvolatile semiconductor memory to the second storing area and the third storing area in a logical block unit associated with one or more blocks. The second storing area is configured to be managed with a first management unit. The third storing area is configured to be managed with a second management unit, a size of the second management unit being larger than a size of the first management unit. When flushing of data from the first storing area to the second storing area or the third storing area is determined, the controller collects, from at least one of the first storing area, the second storing area and the third storing area, data other than the data determined to be flushed and controls the flushing of the data such that a total of the data is a natural number times as large as the block unit as much as possible.

摘要： A controller includes an identification information management table that manages identification information indicating, for each of addresses in second-management unit, whether one or more data in first management unit belonging to the addresses is stored in the second or the third storing area. When the controller executes a process of flushing data from the first storing area to the second storing area or the third storing area, the controller updates the identification information in the identification information management table. The controller executes a process of reading data from the second storing area or the third storing area by referring to the identification information. As a result, the speed of searches conducted in the management table is increased.

摘要： A method of controlling a nonvolatile semiconductor memory including a plurality of blocks, each one of the plurality of blocks being a unit of data erasing, includes determining a monitored block as a candidate for refresh operation from among the plurality of blocks based on a predetermined condition. The method includes monitoring an error count of data stored in the monitored block and not monitoring an error count of data stored in blocks excluding the monitored block among the plurality of blocks. The method also includes performing the refresh operation on data stored in the monitored block in which the error count is larger than a first threshold value.

摘要： According to one embodiment, a disk array control device manages a plurality of drives as a single logical drive. The disk array control device includes a first register configured to store a to-be-accessed drive number which is designated by a host, and a control module. The control module is configured to receive a command from the host, determine whether the received command is a predetermined command which is used for maintenance of each of the drives, and execute, in a case where the received command is the predetermined command, a pass-through process of sending the received command to the drive which is designated by the to-be-accessed drive number in the first register.
