    • A data control apparatus includes a mapping-table managing unit that manages a mapping table that is associated with a corrupted-data recovery function of recording data and error correcting code data as redundant data that is given separately from the data, distributed and stored in units of stripe blocks in the plural nonvolatile semiconductor memory devices, the mapping table containing arrangement information of the data and the error correcting code data; a determining unit that determines whether to differentiate frequencies of writing the data into the semiconductor memory devices; and a changing unit that changes the arrangement information by switching the data stored in units of the stripe blocks managed using the mapping table to differentiate the frequencies of writing the data into the semiconductor memory devices, when the determining unit determines that the frequencies of writing the data into the semiconductor memory devices are to be differentiated.
    • 数据控制装置包括映射表管理单元,其管理与记录数据的损坏数据恢复功能和纠错码数据相关联的映射表,作为与数据分开地分配并以单元分布和存储的冗余数据 所述多个非易失性半导体存储器件中的条形块,所述映射表包含所述数据的排列信息和所述纠错码数据; 确定单元,其确定是否将写入数据的频率区分成半导体存储器件; 以及改变单元,其通过切换存储在使用映射表管理的条带块的单元中的数据来改变排列信息,以将写入数据的频率区分为半导体存储器件,当确定单元确定写入的频率 差分数据到半导体存储器件中。
