    Patent number: 7395975
    Abstract: An SD memory card contains an RF circuit, a controller LSI and a flash memory. The RF circuit is connected to an antenna module attached to the SD memory card. The controller LSI executes radio interface control and interface control for the SD memory card. By running a protocol control program and an SD memory card interface control program stored in a ROM, using an MPU, the controller LSI executes upper-protocol control and SD memory card interface control (security data access control, flash memory access control).
