    Abstract: A semiconductor device with a reduced area and capable of higher integration and larger storage capacity is provided. A multi-valued memory cell including a reading transistor which includes a back gate electrode and a writing transistor is used. Data is written by turning on the writing transistor so that a potential according to the data is supplied to a node where one of a source electrode and a drain electrode of the writing transistor and a gate electrode of the reading transistor are electrically connected to each other, and then turning off the writing transistor and holding a predetermined potential in the node. Data is read by supplying a reading control potential to a control signal line connected to one of a source electrode and a drain electrode of the reading transistor, and then detecting potential change of a reading signal line.

    Abstract: A signal processing circuit that consumes less power by stop of supply of power for a short time. In a storage element, before supply of power is stopped, data in a first storage circuit is stored to a second storage circuit, and the data is read from the second storage circuit and a verification circuit can determine whether or not the data in the second storage circuit matches the data in the first storage circuit. After supply of power is restarted, the data in the second storage circuit is stored to the first storage circuit, and the verification circuit can determine whether or not the data in the second storage circuit matches the data in the first storage circuit. In such a manner, verification can be performed without requiring a time for verification.

    Abstract: To provide a power feeding system and the like with which charging can be performed without a decrease in the power supply efficiency. To provide a power feeding system and the like with which can offer a power feeding service which is efficient to both a power feeding user and a power feeding provider. The power transmission state in each of power transmitting portions is monitored, the power transmitting portion having the highest power transmission efficiency is selected based on positional advantage, and the power transmitting resonance coil included in the selected power transmitting portion is kept at a first resonance frequency, whereby power transmission continues. The resonance frequency of the power transmitting resonance coil included in the non-selected power transmitting portion (the number of the non-selected power transmitting portions may be plural) is set to a second resonance frequency, whereby power transmission is stopped.
