1. An IC card for insertion into a card slot of a host device, comprising:
- a radio frequency circuit;
a flash memory chip;
a plurality of signal pins, which are configured for connection to the host device inside the card slot and include a data pin that receives data from the host device;
a controller chip, which (i) is separate from the flash memory chip;
(ii) is configured to control access to the flash memory chip and to control the radio frequency circuit; and
(iii) writes the data received through the data pin in the flash memory chip; and
a connector, which (i) is connected to the radio frequency circuit;
(ii) is attachable to and detachable from an antenna provided in the host device;
(iii) is provided on a side of the IC card where the plurality of signal pins connect to the host device; and
(iv) contacts the antenna inside the card slot if the IC card is inserted into the card slot, the radio frequency circuit being detached from the antenna if the IC card is removed from the card slot.

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).
