Abstract: A storage device writes data at a high speed. The storage device is provided with a data area and a control unit. In the data area, a write position is specified by a write address. Also, the control unit writes the data in the write address when instructed to write the data in the write address, and generates an address different from the write address in which the writing is performed as an alternative write address and writes the data in the alternative write address when the writing of the data is unsuccessful.

Abstract: The convenience of an information processing system is improved. In a memory controller of the information processing system, a request generation unit generates, with respect to a nonvolatile memory including a data area in which data is stored and a redundancy area in which a redundancy for performing error detection and error correction of the data is stored, a request of requesting writing or reading for any one of the data, and the redundancy, a code word constituted of the data and the redundancy. A control unit issues the generated request and controls writing and reading with respect to the nonvolatile memory.
