    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.

    摘要： A memory system includes a nonvolatile memory including blocks as data erase units, a measuring unit which measures an erase time at which data in each block is erased, a block controller having a block table which associates a state value indicating one of a free state and a used state with the erase time for each block, a detector which detects blocks in which rewrite has collectively occurred within a short period, a first selector which selects a free block having an old erase time as a first block, a second selector which selects a block in use having an old erase time as a second block, and a leveling unit which moves data in the second block to the first block if the first block is included in the blocks detected by the detector.

    摘要： A controller determines whether data stored in a first storing area should be flushed to a second storing area or a third storing area. When flushing of data in a track unit from at least one of the first storing area and the second storing area unit to the third storing area unit is determined, the controller collects data included in the flushed data in the track unit from at least one of the first storing area and the second storing area including the storing area from which the flushing of the data is determined, merges the flushed data and the collected data, and writes the merged data in the third storing area.
