1. a kind of terminal device, comprising:

  • Basic unit of storage, configuration carry out memory system data and apply data;

    At least two additional memory units configure to store program data and user data;

    Processing unit configures to run operating system, and manages the basic unit of storage and at least two additional storagesUnit,Wherein when at least two additional memory unit is loaded by the operating system, do not needing to each of operating systemIn the case that a interface is modified, the processing unit loads at least two additional storages list with identical mount pointMember;

    Wherein at least two additional memory unit includes the first additional memory unit and the second additional memory unit;

    AndFirst additional memory unit is defaulted as preferentially storing depositing for application data and user data by the processing unitStorage unit is loaded in first additional memory unit and the second additional memory unit by the operating system, and describedWhen the usable space of first additional memory unit is less than preset threshold, the processing unit is by the application program of subsequent installationProgram data and user data are stored in second additional memory unit, andIt is loaded in first additional memory unit and the second additional memory unit by the operating system, and described firstWhen the usable space of additional memory unit is less than preset threshold, the processing unit will be deposited in first additional memory unitThe program data of the application program of storage and a part of user data copy in second additional memory unit, and are based onInstitute'"'"'s version data and a part of user data second additional memory unit actual address, described in modificationMapping relations between actual address and the logical address of institute'"'"'s version data and a part of user data.
