A communication circuit chip includes a controller, a power manager, and a memory. The controller selectively communicates, based on a reception signal that is received through an antenna, with one memory card among first and second memory cards. The power manager transfers power, in response to receiving the reception signal through the antenna, to the one memory card that is selected to communicate with the controller. The memory stores content data such that content of data stored in each of the first and second memory cards is recognized. The controller selects the one memory card that is to communicate with the controller from among the first and second memory cards, with reference to the stored content data.
