Interface IC and memory card including the same
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 at least one transmitter are provided in a single IC (integrated circuit) chip and are not overlapped with each other in a planar view.
1. A memory card comprising:
a memory that stores data;
a driver that transmits the data received from the memory;
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 at least one transmitter are provided in a single IC (integrated circuit) chip and are not overlapped with each other in a planar view; and
a clock receiver that receives a clock signal from the external main unit,
wherein a size of the at least one transmitter differs from a size of the clock receiver.
2. The memory card according to claim 1 , wherein the at least one transmitter comprises a coil.
3. The memory card according to claim 1 , wherein the at least one transmitter comprises a plurality of transmitters.
4. The memory card according to claim 3 , wherein the plurality of transmitters transmit the data to the receiver alternately.
5. The memory card according to claim 3 , wherein the plurality of transmitters transmit the data to the receiver randomly.
6. 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.
7. The memory card according to claim 6 , wherein the encrypting circuit is provided in the IC chip.
8. The memory card according to claim 1 , wherein the memory is provided in the IC chip.
9. The memory card according to claim 1 , wherein the data stored in the memory comprises a game software.
10. The memory card according to claim 1 , wherein the driver is not overlapping by being stacked above the at least one transmitter in a planar view.
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;
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 at least one transmitter are provided in a single IC chip and are not overlapped with each other in a planar view; and
a clock receiver that receives a clock signal from the main unit and is provided in the IC chip.
12. The interface IC according to claim 11 , wherein the at least one transmitter comprises a coil.
13. The interface IC according to claim 11 , wherein the at least one transmitter comprises a plurality of transmitters.
14. The interface IC according to claim 13 , wherein the plurality of transmitters transmit the data to the receiver alternately.
15. The interface IC according to claim 13 , wherein the plurality of transmitters transmit the data to the receiver randomly.
16. The interface IC according to claim 11 , wherein a size of the at least one transmitter differs from a size of the clock receiver.
17. The interface IC according to claim 11 , wherein the driver is not formed over the at least one transmitter in a planar view.
