Semiconductor device

A semiconductor device being embeddable in a living body, comprising a communication portion, a control portion, a memory portion, an arithmetic portion, and a sensor portion,

• wherein the memory portion is configured to retain identification information,
• wherein the arithmetic portion is configured to retain first information, and to use the first information and second information supplied from the sensor portion to generate third information,
• wherein the control portion is configured to output, through the communication portion to the outside, one or both of the identification information and the third information, in response to a signal input through the communication portion,
• wherein the arithmetic portion comprises an arithmetic circuit and a memory circuit provided over the arithmetic circuit, the memory circuit comprising a transistor comprising an oxide semiconductor in a channel formation region,
• wherein the semiconductor device is covered with a coating material,
• wherein each of the communication portion, the control portion, the memory portion, the arithmetic portion, and the sensor portion are provided over the coating material, and
• wherein each of the communication portion, the control portion, the memory portion, the arithmetic portion, and the sensor portion do not overlap each other.
