A semiconductor device with improved convenience is provided by having an antenna for converting an electromagnetic wave into an electric signal, a detecting portion for detecting chemical reaction, and a control portion for controlling the antenna and the detecting portion. The detecting portion includes at least a detecting element, and the control portion includes at least a transistor. The detecting element includes a reactive layer for solidifying at least any one of a nucleic acid, a protein, an enzyme, an antigen, an antibody and a microbe. Alternatively, a semiconductor device includes an antenna, a detecting portion, a control portion, and a memory portion. The memory portion includes at least a memory element, and the memory element includes a first conductive layer, a second conductive layer, and a layer between the first conductive layer and the second conductive layer.
