Semiconductor device

摘要

To supply a signal in which the occurrence of delays is prevented to a storage circuit. To provide a novel semiconductor device in which a load applied to a logic circuit is low. The following structure is completed: a storage circuit to which a plurality of data signals and a selection signal are supplied connects two combination circuits, and a storage circuit has a function of selecting one of a plurality of data signals in accordance with the selection signal. A selection circuit is not necessarily provided between the storage circuit and the combination circuit. As a result, the combination circuit can supply a signal in which the occurrence of delays is prevented to the storage circuit.
