Abstract

Claims (51)

1. A method for performing a download operation, comprising:

detecting an updated firmware for installation, wherein the updated firmware is disposed in a data storage device;

transmitting at least one slice of the updated firmware from an updated firmware location of the data storage device to a second firmware location of the data storage device;

determining if a synchronization has completed with the at least one slice of the updated firmware;

determining if additional slices are to be synchronized when the synchronization has completed with the at least one slice of the updated firmware;

sending at least one additional slice of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device when the determining if the additional slices are to be synchronized when the synchronization has completed with the at least one slice of the updated firmware; and

performing a synchronization of the at least one additional slice of the updated firmware.

2. The method according to claim 1 , wherein the detecting the updated firmware for installation is performed by a processor.

3. The method according to claim 2 , wherein the processor is a main processor.

4. The method according to claim 1 , wherein the second firmware location is a NOR memory.

5. The method according to claim 1 , wherein the transmitting the at least one slice of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device is performed by a processor.

6. The method according to claim 5 , wherein the processor is a dedicated processor.

7. The method according to claim 1 , wherein the performing the synchronization of the at least one additional slice of the updated firmware is performed by a dedicated processor.

8. The method according to claim 1 , further comprising:

continuing a synchronization of the slice when the determining of a synchronization has completed with the at least one slice of the updated firmware.

9. An arrangement for performing a download operation, comprising:

processor means for detecting an updated firmware disposed in a data storage device for installation;

processor means for transmitting at least one slice of the updated firmware from an updated firmware location of the data storage device to a second firmware location of the data storage device;

processor means for determining if a synchronization has completed with the at least one slice of the updated firmware;

processor means for determining if additional slices are to be synchronized when the synchronization has completed with the at least one slice of the updated firmware; and

processor means for sending at least one additional slide of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device when the determining if the additional slices are to be synchronized when the synchronization has completed with the at least one slice of the updated firmware.

10. A method for performing a download operation for a data storage device, comprising:

using a processor, detecting an updated firmware for installation disposed in an updated firmware location of the data storage device;

transmitting at least one slice of the updated firmware from the updated firmware location of the data storage device to a second firmware location of the data storage device;

performing a synchronization of the at least one slice of the updated firmware to form a copy of the updated firmware;

determining after synchronization if the copy of the updated firmware is completed;

transmitting further slices of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device; and

performing a second synchronization of the further slices of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device until the updated firmware is completed.

11. The method according to claim 10 , further comprising:

loading the updated firmware.

12. The method according to claim 11 , further comprising:

erasing firmware that was not the updated firmware.

13. The method according to claim 10 , wherein the second firmware location is a NOR memory.

14. The method according to claim 10 , wherein the transmitting the at least one slice of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device is along a bus.

15. The method according to claim 10 , further comprising:

downloading an updated firmware to the updated firmware location of the data storage device.

16. The method according to claim 10 , wherein the data storage device is a solid state drive.

17. The method according to claim 10 , wherein the processor is a main processor for the data storage device.

18. The method according to claim 10 , wherein the updated firmware is from a host.

19. The method according to claim 18 , wherein the host is a one of a personal computer, a server, a music device and a computer tablet.

20. An arrangement for performing a download operation comprising:

processor means for detecting an updated firmware for installation in an updated firmware location of a data storage device;

processor means for transmitting at least one slice of the updated firmware from the updated firmware location of the data storage device to a second firmware location of the data storage device;

processor means for performing a synchronization of the at least one slice of the updated firmware to form a copy of the updated firmware;

processor means for determining after synchronization if the copy of the updated firmware is completed;

processor means for transmitting further slices of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device; and

processor means for performing a second synchronization of the further slices of the updated firmware from the updated firmware location of the data storage device to the second firmware location of the data storage device until the updated firmware is completed.

21. The arrangement according to claim 20 , further comprising:

processor means for transmitting data from the updated firmware location of the data storage device to the second firmware location of the data storage device.

22. The arrangement according to claim 20 , further comprising:

processor means for erasing firmware from the updated firmware location of the data storage device.
