摘要：
A card-shaped memory device includes a power supply terminal, an antenna terminal, a control circuit, a power generating circuit, and a switching circuit. The power supply terminal is provided to receive power supplied from a host device. The antenna terminal is connected to a non-contact communication antenna provided at the host device, and receives a signal from the antenna. The control circuit has a wireless communication function and an IC card function. The power generating circuit is included in the control circuit, and generates power based on the signal from the antenna. The switching circuit is included in the control circuit, and effects switching between supplying of power from the power supply terminal and supplying of power from the power generating circuit.
