Abstract

In some embodiments an interface of a portable memory device is used to store content information in a hidden memory region of the portable memory device. The interface is also used to store information in a visible memory region of the portable memory device. The information stored in the visible memory region allows the content information stored in the hidden memory region to be accessed. Other embodiments are described and claimed.

Claims

1. A portable memory device comprising:

a hidden memory region;

a visible memory region;

a first interface to store content information in the hidden memory region and to store information in the visible memory region, wherein the information stored in the visible region allows the content information stored in the hidden region to be accessed.

2. The portable memory device of claim 1, wherein the first interface is further to read the information from the visible memory region in order to provide the content information from the hidden memory region to a media player to be coupled to the portable memory device via the first interface while maintaining content protection of the content information.

3. The portable memory device of claim 1, further comprising a second interface to read the information from the visible memory region in order to provide the content information from the hidden memory region to a media player to be coupled to the portable memory device via the second interface while maintaining content protection of the content information.

4. The portable memory device of claim 3, wherein the first interface is an interface to be used only by a supplier of the content information to be stored in the hidden memory region of the portable memory device.

5. The portable memory device of claim 1, wherein the first interface is an interface to be used by a user to play the content information stored in the hidden memory region of the portable memory device while maintaining content protection of the content information.

6. The portable memory device of claim 1, wherein the portable memory device is a flash memory device.

7. The portable memory device of claim 1, wherein the first interface is at least one of a fast flash interface, a SATA interface, or a USB interface.

8. The portable memory device of claim 3, wherein the first interface and the second interface do not allow simultaneous access of the portable memory device.

9. The portable memory device of claim 1, the first interface to scrub the hidden memory region prior to storing the content information in the hidden memory region.

10. The portable memory device of claim 1, wherein the first interface is to store the content information in the hidden memory region using one atomic operation.

11. The portable memory device of claim 1, wherein the first interface has write only access to the hidden memory region.

12. A method comprising:

storing content information in a hidden memory region of a portable memory device using a first interface of the portable memory device; and

storing information in a visible memory region of the portable memory device using the high speed interface, wherein the information stored in the visible region allows the content information stored in the hidden region to be accessed.

13. The method of claim 12, further comprising accessing the information stored in the visible memory region to allow playing of the content information in the hidden memory region while maintaining content protection of the content information.

14. The method of claim 12, wherein the storing of content information in the hidden memory region and the storing of information in the visible memory region is only performed by a supplier of the content information.

15. The method of claim 12, wherein the storing of information in the visible memory region includes storing code information in the visible memory region that may be used to access the content information stored in the hidden memory region.

16. The method of claim 12, further comprising playing the content information stored in the hidden memory region of the portable memory device using the information stored in the visible memory region while maintaining content protection of the content information.

17. The method of claim 12, further comprising accessing the information from the visible memory region to play the content information from the hidden memory region via a second interface while maintaining content protection of the content information.

18. The method of claim 17, further comprising never allowing the first interface and the second interface to simultaneously access the portable memory device.

19. The method of claim 12, further comprising scrubbing the hidden memory region prior to storing the content information in the hidden memory region.

20. The method of claim 12, further comprising storing the content information in the hidden memory region using one atomic operation.

21. The method of claim 12, wherein the first interface has write only access to the hidden memory region.

22. An article comprising:

a computer readable medium having instructions thereon which when executed cause a computer to;

store content information in a hidden region of a portable memory device using a high speed interface of the portable memory device; and

store information in a visible region of the portable memory device using the high speed interface, wherein the information stored in the visible region allows the content information stored in the hidden region to be accessed.

23. The article of claim 22, the computer readable medium further having instructions thereon which when executed cause a computer to store code information in the visible memory region that may be used to access the content information stored in the hidden memory region.

24. The article of claim 22, the computer readable medium further having instructions thereon which when executed cause a computer to scrub the hidden memory region prior to storing the content information in the hidden memory region.

25. The article of claim 22, the computer readable medium further having instructions thereon which when executed cause a computer to store the content information in the hidden memory region using one atomic operation.

26. The article of claim 22, the computer readable medium further having instructions thereon which when executed cause a computer to access the information stored in the visible memory region to allow playing of the content information in the hidden memory region while maintaining content protection of the content information.

27. The article of claim 22, wherein the high speed interface has write only access to the hidden memory region.
