Abstract: There is provided a control device including, a reading and writing control unit configured to control writing and reading of data on and from a non-volatile memory that has a plurality of blocks each set to be a unit for performing erasure of data. The non-volatile memory stores order information indicating an order of the blocks in which data is to be written. The reading and writing control unit selects a writing target block that is a target block for writing of data according to the order indicated by the order information, and writes data in the selected writing target block.

Abstract: There is provided an information processing apparatus including a rewrite frequency management section configured to manage a rewrite frequency of a page included in a nonvolatile primary storage apparatus having an upper limit in the rewrite frequency, and a data processing section configured, when an instruction for writing write data to a predetermined page is issued and a rewrite frequency of the predetermined page reaches a threshold value that is less than the upper limit of the rewrite frequency of the primary storage apparatus, to write the write data to another page different from the predetermined page, the other page storing no effective data and having a rewrite frequency that does not reach the threshold value.

Abstract translation: 提供了一种信息处理设备，包括：重写频率管理部分，被配置为管理包含在重写频率上限的非易失性主存储装置中的页面的重写频率;以及数据处理部件，当写入指令时 写入数据到预定页面，并且预定页面的重写频率达到小于主存储装置的重写频率的上限的阈值，以将写入数据写入与预定页面不同的另一页面 ，另一页不存在有效数据并且具有未达到阈值的重写频率。

Abstract: There is provided a memory management device including a non-volatile memory that performs writing and reading of data on a per-page basis, and performs erasing on a per-block basis, and a control unit that manages a data process in the non-volatile memory by performing logical-physical translation on a per-translation unit (TU) basis, and performs a fold process. The control unit sets data of a physical TU corresponding to unnecessary logical TU information to be excluded from a copy target in the fold process based on the unnecessary logical TU information, the unnecessary logical TU information being notified of by a file system and representing a logical TU corresponding to a physical TU in which unnecessary data is physically written.

Abstract translation: 提供了一种存储器管理装置，包括：以每页为单位执行数据的写入和读取的非易失性存储器，并且以每个块为基础执行擦除;以及控制单元，其管理非易失性存储器中的数据处理， 通过在每个翻译单元（TU）的基础上执行逻辑 - 物理转换，并进行折叠处理。 控制单元基于不需要的逻辑TU信息，在折叠处理中，将与不需要排除的不必要的逻辑TU信息对应的物理TU数据设定为由文件系统通知的不必要的逻辑TU信息，并表示逻辑 TU对应于物理TU，其中不需要的数据被物理地写入。
