Abstract: A novel electronic device including a reconfigurable circuit is provided. In the electronic device including a reconfigurable circuit capable of executing multi-context operation, a context selection signal is locally generated. For example, a context selection signal is generated in the reconfigurable circuit with the use of context determination data contained in an output of another logic block, for example. The range of application of the context selection signal can be set as appropriate by a user. Thus, multi-context operation performed locally and partly enables efficient use of the circuit. Memory usage can be reduced and its efficiency can be improved compared to the case of using global multi-context driving. Other embodiments may be disclosed and claimed.

Abstract: A semiconductor device that has low power consumption and is capable of performing a product-sum operation is provided. The semiconductor device includes first and second cells, a first circuit, and first to third wirings. Each of the first and second cells includes a capacitor, and a first terminal of each of the capacitors is electrically connected to the third wiring. Each of the first and second cells has a function of feeding a current based on a potential held at a second terminal of the capacitor, to a corresponding one of the first and second wirings. The first circuit is electrically connected to the first and second wirings and stores currents I1 and I2 flowing through the first and second wirings. When the potential of the third wiring changes and accordingly the amount of current of the first wiring changes from I1 to I3 and the amount of current of the second wiring changes from I2 to I4, the first circuit generates a current with an amount I1−I2−I3+I4. Note that the potential of the third wiring is changed by firstly inputting a reference potential to the third wiring and then inputting a potential based on internal data or a potential based on information obtained by a sensor.
