Abstract
Objects of the invention are to provide a semiconductor device including an RFID, which can transmit and receive individual information without a check of remaining capacity of the battery and a change of the battery in accordance with deterioration over time of the battery for a driving power supply; and which maintains a favorable communication state even when electric power, as a power supply for driving, from an external radio wave or electromagnetic wave (carrier wave) is not sufficient. A battery is provided as a power supply for supplying electric power in the RFID, and electric power obtained by a power generation element is charged in the battery.
