Abstract:
A signal processing unit with reduced power consumption is provided. A transistor in which a channel is formed in an oxide semiconductor is used for a storage circuit included in the signal processing unit, so that data can be held (stored) even while supply of power is stopped. Non-destructive reading can be performed on the data stored in the storage circuit even when supply of power to the signal processing unit is stopped.
