A signal processing circuit capable of suppressing power consumption without requiring a complicated manufacturing process is provided. Two logic elements (first phase inverting element and second phase inverting element) for inverting the phase of an input signal, a first selection transistor, and a second selection transistor And two sets of a transistor and a capacitor in which a channel is formed in an oxide semiconductor layer (a pair of a first transistor and a first capacitor, and a second transistor) And a second capacitor element). The above memory element is used for a memory device included in the signal processing circuit. For example, the storage element is used for a storage device such as a register or a cache memory included in the signal processing circuit. [Selection] Figure 1 |
