Abstract

A memory card includes a memory that stores data, a driver that transmits the data received from the memory, and at least one transmitter that transmits the data received from the driver to a receiver provided in an external main unit. The driver and the transmitter are provided in a single IC (Integrated Circuit) chip and are not overlapped with each other in planar view, and the transmitter includes a coil.

Claims (35)

1. A memory card comprising:

a memory that stores data;

a driver that transmits the data received from the memory; and

at least one transmitter that transmits the data received from the driver to a receiver provided in an external main unit,

wherein the driver and the transmitter are provided in a single IC (Integrated Circuit) chip and are not overlapped with each other in planar view, and

wherein the transmitter comprises a coil.

2. The memory card according to claim 1 , wherein the at least one transmitter comprises a plurality of transmitters.

3. The memory card according to claim 2 , wherein the plurality of transmitters transmit the data to the receiver alternately.

4. The memory card according to claim 2 , wherein the plurality of transmitters transmit the data to the receiver randomly.

5. The memory card according to claim 1 , further comprising a clock receiver that receives a clock signal from the external main unit.

6. The memory card according to claim 5 , wherein the size of the transmitter differs from the size of the clock receiver.

7. The memory card according to claim 1 , further comprising an encrypting circuit that encrypts the data received from the memory and transmits the encrypted data to the driver.

8. The memory card according to claim 7 , wherein the encrypting circuit is provided in the IC chip.

9. The memory card according to claim 1 , wherein the memory is provided in the IC chip.

10. The memory card according to claim 1 , wherein the data stored in the memory is a game software.

11. An interface IC (Integrated Circuit) provided in a memory card so as to transmit data from the memory card to a main unit into which the memory card is inserted, the interface IC comprising:

a driver that transmits the data received from a memory of the memory card; and

at least one transmitter that transmits the data received from the driver to a receiver provided in the main unit,

wherein the driver and the transmitter are provided in a single IC chip and are not overlapped with each other in planar view, and

wherein the transmitter comprises a coil.

12. The interface IC according to claim 11 , wherein the at least one transmitter comprises a plurality of transmitters.

13. The interface IC according to claim 12 , wherein the plurality of transmitters transmit the data to the receiver alternately.

14. The interface IC according to claim 12 , wherein the plurality of transmitters transmit the data to the receiver randomly.

15. The interface IC according to claim 11 , further comprising a clock receiver that receives a clock signal from the main unit and is provided in the IC chip.

16. The interface IC according to claim 15 , wherein the size of the transmitter differs from the size of the clock receiver.

17. A semiconductor apparatus, comprising:

a non-transitory computer readable media that stores data;

a driver that transmits the data received from the non-transitory computer readable media; and

at least one transmitter that transmits the data received from the driver to a receiver provided in an external main unit,

wherein the driver and the transmitter are provided in a single IC (Integrated Circuit) chip and are not overlapped with each other in planar view, and

wherein the transmitter comprises a coil.

18. The semiconductor apparatus according to claim 17 , wherein the at least one transmitter comprises a plurality of transmitters that transmit the data to the receiver alternately or randomly.

19. The semiconductor apparatus according to claim 17 , wherein the transmitter transmits the data to the receiver alternately or randomly.

20. The semiconductor apparatus according to claim 17 , further comprising a clock receiver that receives a clock signal from the external main unit, and

wherein the size of the transmitter differs from the size of the clock receiver.
