Patent abstract
To provide a semiconductor device that is capable of displaying data even when a radio signal is not supplied. The semiconductor device includes an antenna, a battery, a sensor, a nonvolatile memory, a first circuit, and a second circuit. Power supplied from the antenna is converted into first power via the first circuit. The battery stores the first power and supplies second power. The sensor performs sensing with the second power. The nonvolatile memory stores analog data acquired by the sensor. The second power is used to store the analog data. The second circuit converts the analog data into digital data with the use of the first power. The nonvolatile memory preferably includes an oxide semiconductor transistor.
