摘要： A memory system includes a volatile first storing unit, a nonvolatile second storing unit, and a controller. The controller performs data transfer, stores management information including a storage position of the data stored in the second storing unit into the first storing unit, and performs data management while updating the management information. The second storing unit has a management information storage area for storing management information storage information including management information in a latest state and a storage position of the management information. The storage position information is read by the controller during a startup operation of the memory system and includes a second pointer indicating a storage position of management information in a latest state in the management information storage area and a first pointer indicating a storage position of the second pointer. The first pointer is stored in a fixed area in the second storing unit and the second pointer is stored in an area excluding the fixed area in the second storing unit.

摘要： A controller stores therein a sector address set indicating logical storage positions within a nonvolatile-memory storage area; page addresses indicating, in units of pages, physical storage positions within the nonvolatile-memory storage area; and pieces of management information each indicating whether one or more special sectors each being either a bad sector or a trimmed sector trimmed by a TRIM command are present in the corresponding page, while associating them with each other. When an access to a specified sector address is requested, the device refers to the piece of management information and judges whether any special sector is present in the page identified by the page address corresponding to the sector address. The device generates predetermined response data if the page contains one or more special sectors and accesses the nonvolatile-memory storage position corresponding to the sector address if the page contains no special sector.

摘要： An apparatus according to an embodiment comprises a first storage, a second storage, an input unit, a shift number determining unit, and an output unit. The first storage stores identification information of sectors and defective information indicating a presence of defect on the data line, while associating the identification information and the defective information. The second storage has storage regions in a number larger than the first number. The input unit inputs data to the second storage by the first number at a time. The shift number determining unit determines a shift number. The output unit outputs the data stored in the storage regions which is after a head storage region by the shift number, as the data is to be supplied to the data line having no defect sector based upon the defective information, and outputs information that differs from the data to the defective data line.

摘要： According to an embodiment, a memory system includes semiconductor memories each having a plurality of blocks; a first table; a receiving unit; a generating unit; a second table; and a writing unit. The first table includes a plurality of memory areas each associated with each block and in each of which defect information is stored. The generating unit generates a set of blocks by selecting one block to which data are to be written in each semiconductor memory based on an index number indicating one of a plurality of rows in the first table and the first table. In the second table, an index number and a channel number are stored for each logical block address in association with one another. When a write command is received by the receiving unit, the writing unit writes data to a block associated with a selected channel number among blocks constituting the set.

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.
