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).

Claims

1-12. -12. (Canceled)

13. An IC card for insertion into a card slot of a host device, comprising:

a radio frequency circuit;

a flash memory chip;

a controller chip, being separate from the flash memory chip, configured to control access to the flash memory chip and to control the radio frequency circuit; and

a connector connected to the radio frequency circuit and attachable to and detachable from an antenna located outside the IC card, wherein the radio frequency circuit is detached from the antenna if the IC card is removed from the card slot.

14. The IC card according to claim 13, wherein the controller chip is capable of providing a security data access control.

15. The IC card according to claim 14, wherein the security data access control involves a personal identification.

16. The IC card according to claim 15, wherein the personal identification uses an identification data stored in the IC card.

17. The IC card according to claim 16, wherein the controller chip includes an SD card interface.
