Abstract: A data storage device includes a nonvolatile memory device, a storage controller and a mapping controller. The nonvolatile memory device stores an execution code that controls operations of the data storage device. The storage controller uploads and stores the execution code from the nonvolatile memory device to a host memory buffer included in an external host device, and downloads the execution code in realtime from the host memory buffer to execute the execution code that is downloaded from the host memory buffer. The mapping controller manages a mapping table including mapping relations between the execution code and host addresses of the host memory buffer at which the execution code is stored. A speed of accessing the execution code is increased and performance of the data storage device is enhanced by using the host memory buffer as storage of the execution code to control the operation of the data storage device.

Abstract: A method for controlling a plurality of batteries and an electronic device thereof are provided. The electronic device includes a power management circuit configured to supply power to the electronic device; a first battery electrically connected with a power input port of the power management circuit; a second battery electrically connected with the power input port; a first charging circuit configured to charge the first battery; a second charging circuit configured to charge the second battery; a first current control circuit electrically connected between the first charging circuit and the first battery, and configured to control a first charging current supplied from the first charging circuit to the first battery and a leakage current due to a voltage difference between the first battery and the second battery; and a second current control circuit electrically connected between the second charging circuit and the second battery, and configured to control a second charging current supplied from the second charging circuit to the second battery and the leakage current.
