    摘要： In one embodiment, a memory system for writing redundant data output by an encoding processing circuit, comprises a memory, a encoding processing circuit, and a decoding circuit. The memory is electrically rewritable by using memory cells. The memory cells are capable of having two different resistance values corresponding to logical values of 1 or 0 respectively. The redundant data is read from and a predetermined logical value is written to the memory by flowing current in a same direction. The encoding processing circuit performs redundant encoding processing on target data and outputs redundant data. A number of bits having the predetermined logical value exceeds a number of bits having the logical value other than the predetermined logical value, for writing the redundant data to the memory. A decoding circuit reads data from the memory, and performs a decoding process on the data.

    摘要： According to one embodiment, a semiconductor device includes a processor, and a memory device. The memory device has a nonvolatile semiconductor storage device and is configured to serve as a main memory for the processor. When the processor executes a plurality of programs, the processor manages pieces of information required to execute the programs as worksets for the respective programs, and creates tables, which hold relationships between pieces of information required for the respective worksets and addresses of the pieces of information in the memory device, for the respective worksets. The processor accesses to the memory device with reference to the corresponding tables for the respective worksets.

    摘要： According to one embodiment, a storage device management device is connected to a random access memory and a first storage device. When the random access memory includes a free region sufficient to store write data, the write data is stored onto the random access memory. Data on the random access memory selected in the descending order of elapsed time from the last access is sequentially copied onto the first storage device, and a region in the random access memory which has stored the copied data is released. When stored on the random access memory, the read data is read from the random access memory to the processor. When stored on the first storage device, the read data is copied onto the random access memory and read from the random access memory to the processor.
