Semiconductor device
A semiconductor device with a novel structure in which storage capacity needed for holding data can be secured even with miniaturized elements is provided. In the semiconductor device, electrodes of a capacitor are an electrode provided in the same layer as a gate of a transistor and an electrode provided in the same layer as a source and a drain of the transistor. Further, a layer in which the gate of the transistor is provided and a wiring layer connecting the gates of the transistors in a plurality of memories are provided in different layers. With this structure, parasitic capacitance formed around the gate of the transistor can be reduced, and the capacitor can be formed in a larger area.
