    • A memory system includes a volatile first storing unit, a nonvolatile second storing unit, and a controller. The controller performs data transfer, stores management information including a storage position of the data stored in the second storing unit into the first storing unit, and performs data management while updating the management information. The second storing unit has a management information storage area for storing management information storage information including management information in a latest state and a storage position of the management information. The storage position information is read by the controller during a startup operation of the memory system and includes a second pointer indicating a storage position of management information in a latest state in the management information storage area and a first pointer indicating a storage position of the second pointer. The first pointer is stored in a fixed area in the second storing unit and the second pointer is stored in an area excluding the fixed area in the second storing unit.
    • 存储系统包括易失性第一存储单元,非易失性第二存储单元和控制器。 控制器执行数据传送,将存储在第二存储单元中的数据的存储位置的管理信息存储到第一存储单元中,并且在更新管理信息的同时执行数据管理。 第二存储单元具有用于存储管理信息存储信息的管理信息存储区域,该管理信息存储信息包括最新状态的管理信息和管理信息的存储位置。 存储位置信息在存储器系统的启动操作期间由控制器读取,并且包括指示管理信息存储区域中处于最新状态的管理信息的存储位置的第二指针和指示第二存储器的存储位置的第一指针 指针。 第一指针存储在第二存储单元中的固定区域中,并且第二指针存储在除了第二存储单元中的固定区域之外的区域中。
