摘要： According to an embodiment of a controller, a bit string manipulating unit manipulates a bit string of manipulation target data based on a predetermined rule. A special data setting unit generates a magic number based on a special data setting request from a host interface, obtains an error detecting code for the magic number, and sends the magic number and the error detecting code as manipulation target data to the bit string manipulating unit to obtain a manipulated manipulation target data. The special data setting unit also extracts logical block address information from the special data setting request, and instructs an access unit to write the magic number in the manipulated manipulation target data to a user data storage area and to write the error detecting code in the manipulated manipulation target data to a redundant area in a storage area located by the logical block address information.

摘要： According to one embodiment, a memory system includes a non-volatile semiconductor memory, a block management unit, and a transcription unit. The semiconductor memory includes a plurality of blocks to which data can be written in both the first mode and the second mode. The block management unit manages a block that stores therein no valid data as a free block. When the number of free blocks managed by the block management unit is smaller than or equal to a predetermined threshold value, the transcription unit selects one or more used blocks that stores therein valid data as transcription source blocks and transcribes valid data stored in the transcription source blocks to free blocks in the second mode.

摘要： A size storage unit stores therein a block size of a memory element. A buffering unit executes buffer processing configured to store data received from a RAID (Redundant Arrays of Inexpensive/Independent Disks) controller into a buffer, and to write the data stored in the buffer into the memory element. A stripe-size receiving unit receives a stripe size that indicates a size of a unit of access at time of access to the memory element by the RAID controller. Writing processing is configured to write data received from the RAID controller into the memory element without executing the buffer processing by the buffering unit, when the stripe size is n times of the block size (n is a positive integer).

摘要： A volatile management memory stores management information for managing a use state of a storage medium. A management information storing unit divides the management information into plural division pieces and individually stores them in the storage medium. A main controller receives a command from a host device while the division pieces are being stored, performs data processing for the storage medium in response to the command between each division piece is stored, updates the management information divided into the division pieces according to the data processing content, and creates a log representing an update content of the management information. A log storing unit stores the log in the storage medium. A restoring unit reads the division pieces stored in the storage medium to the management memory as the management information, updates the management information according to the log stored in the storage medium, and restores the updated management information.

摘要： According to one embodiment, a controller controls writing into and reading from a storage apparatus that includes a first data-storage unit and a second data-storage unit. The second data-storage unit stores user data and parity data of the user data. The first data-storage unit stores the parity data. The controller includes a parity updating unit and a parity writing unit. When parity data is updated, the parity updating unit writes the updated parity data into the first data-storage unit. When a certain requirement is satisfied, the parity writing unit reads the parity data written in the first data-storage unit, and writes the parity data thus read into the second data-storage unit.
