COMMUNICATION CIRCUIT CHIP AND ELECTRONIC DEVICE CONFIGURED TO COMMUNICATE WITH PLURAL MEMORY CARDS

摘要

The present invention provides a communication circuit chip comprising a controller, a power manager, and a memory. The controller selectively communicates with one of the first and second memory cards based on a received signal received via the antenna. The power manager supplies power to the selected memory card to communicate with the controller in response to receiving the received signal via the antenna. The memory stores content data including information about the content of data stored in each of the first and second memory cards. The controller selects one of the first and second memory cards to communicate with by referring to the content data. According to the present invention, data stored in a memory card that has not been activated can be read. Accordingly, the range of services provided to users is expanded, and user convenience is improved.
