摘要： A storage device includes a non-volatile memory including a plurality of memory blocks and a storage controller configured to control a read operation of the non-volatile memory. The storage controller receives power-off time information indicating a power-off time point at which the storage device is powered off, and power-on time information indicating a power-on time point at which the storage device is powered on, when the storage device is switched from a power-off state to a power-on state. The storage controller stores a power-off time stamp corresponding to the power-off time point and a power-on time stamp corresponding to the power-on time point in the non-volatile memory.

摘要： An electronic device is provided. The electronic device includes a first processor configured to perform wireless communication with a local area data network (LADN), and a second processor electrically connected with the first processor. The first processor is configured to receive a first message from the LADN indicating that a wireless communication session with the LADN is deactivated because the electronic device has departed from a geographic service area of the LADN, after receiving the first message, and transmit a second message to the second processor indicating that the wireless communication session is deactivated. The second processor is configured to terminate generation of a data packet for uplink transmission after receiving the second message.
