Abstract: The present technology relates to an electronic device. A memory device having improved backup performance according to the present technology includes a memory device including a plurality of logical storage areas, and a memory controller. The memory controller controls the memory device to perform a memory operation on an original storage area of the plurality of logical storage areas according to a request of a host, and to perform a mirroring operation of copying the memory operation which was performed on the original storage area in a backup storage area of the plurality of logical storage areas based on whether the memory device is in an idle state.

Abstract: A memory controller for controlling an operation of a memory device includes a time information buffer and a processing unit. The time information buffer stores a time information mapping table. The processing unit extracts time information from a write command received from a host, and updates the time information mapping table, based on the extracted time information.

Abstract: A method for providing application-related data includes connecting a mobile terminal and a device, determining an object displayed on the mobile terminal, determining a data file associated with the object, and controlling the data file associated with the object to be accessible by the connected device and controlling information of the data file to be displayed on a display of the connected device according to the determination of the object. A terminal that provides application-related data includes a connection unit connecting the terminal and another device to each other; and a synchronization unit, when the connection unit is connected to the another device, synchronizing related data of an application that is in the middle of execution in the terminal or an application selected by a user after the connection with the another device.

Abstract: A localization system includes terminals and a server. The terminal includes an antenna unit to receive a wireless signals, a distance determining unit to determine a distance relative to other terminals using intensity information of the wireless signals, a direction detection unit to obtain an orientation of the terminal, and a control unit to control the terminal. The server includes a calculating unit to calculate a distance between the terminals based on intensity information, and a memory unit to store the distance information. The control unit may calculate a relative location of other terminals using a triangulation method based on the distance information between the terminals. The control unit may determine a location and orientation of another terminal based on a forward direction or orientation of the terminal obtained by the direction detecting unit of the terminal and the relative location of other terminals.

Abstract: A method for authorizing use of Augmented Reality (AR) information includes acquiring information regarding a location at which the AR information is to be provided, authorizing a user to use the AR information, creating attribute information including the AR information, the location information, and authority information, and transmitting the attribute information to an AR system. The AR system can register the attribute information, and can provide the AR information only to authorized users. An apparatus to authorize use of Augmented Reality (AR) information includes a location information acquiring unit, an authorization unit to authorize a user to use the AR information, and an AR information processor to create attribute information. The attribute information is transmitted to an AR system as a request for the AR system to register the attribute information so the AR system provides the AR information only to authorized users.
