    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: According to one embodiment, a memory system includes a nonvolatile memory, a managing unit, an order rule holding unit, a position information storing unit, a list selecting unit, a block selecting unit, a writing unit, and an updating unit. The managing unit holds for each of storage areas of the nonvolatile memory a free block list indicating free blocks. The order rule holding unit holds an order rule used to determine an order of the free block lists. The position information storing unit stores position information indicating the position of the free block list in the order rule. The list selecting unit selects the free block list corresponding to the position indicated by the position information and the block selecting unit selects the free block therefrom. The updating unit updates after the list selection the position information in the position information storing unit with position information indicating the position of the subsequently selected free block list.

    摘要: In an information processing apparatus, when an instruction is issued to write back storage contents of a main memory unit that is non-volatile, data and a write destination address included in a backup data that is set with a read permission are extracted from the backup data stored in a backup memory unit that is non-volatile. Further, according to the data and the write destination address extracted from the backup data, the data is written to a storage area of the main-memory unit indicated by the write destination address.
