Methods to communicate a timestamp to a storage system
Embodiments of methods to communicate a timestamp to a storage system are generally described herein. Other embodiments may be described and claimed.
1. A method comprising:
receiving, by a non-volatile memory storage device, a packet from a computing platform coupled with the non-volatile memory storage device;
processing the packet to use a timestamp included in the packet to determine a time during which the non-volatile memory storage device has been in a powered-down state; and
using the determined time during which the non-volatile memory storage device has been in the powered-down state to calculate a remaining useful life of memory elements included in the non-volatile memory storage device.
2. The method of claim 1 , the powered-down state comprising a powered-off state, a hibernation state, a standby mode or otherwise idled state.
3. The method of claim 1 , comprising the packet sent by the computing platform based on a power-on event or a power-down event.
4. The method of claim 1 , the timestamp comprising a time delta.
5. The method of claim 4 , comprising the time delta indicating a time that has elapsed while the non-volatile memory storage device was in the powered-down state.
6. The method of claim 1 , comprising:
storing the packet in a storage location at the non-volatile memory storage device.
7. The method of claim 6 , comprising storing the packet in the storage location using a log page.
8. The method of claim 1 , the packet comprises a command packet.
9. The method of claim 1 , the memory elements comprising one or more NAND flash memory devices or one or more phase change memory devices.
10. A non-volatile memory storage device comprising:
one or more memory elements; and
a controller to:
receive a packet from a computing platform coupled with the non-volatile memory storage device;
process the packet to use a timestamp included in the packet to determine a time during which the non-volatile memory storage device has been in a powered-down state; and
use the determined time during which the non-volatile memory storage device has been in the powered-down state to calculate a remaining useful life of the one or more memory elements.
11. The non-volatile memory storage device of claim 10 , the powered-down state comprising a powered-off state, a hibernation state, a standby mode or otherwise idled state.
12. The non-volatile memory storage device of claim 10 , comprising the packet sent by the computing platform based on a power-on event or a power-down event.
13. The non-volatile memory storage device of claim 10 , the timestamp comprising a time delta.
14. The non-volatile memory storage device of claim 10 , comprising a time delta to indicate a time that has elapsed while the non-volatile memory storage device was in the powered-down state.
15. The non-volatile memory storage device of claim 10 , comprising:
storing the packet in a storage location at the non-volatile memory storage device.
16. The non-volatile memory storage device of claim 15 , comprising storing the packet in the storage location using a log page.
17. The non-volatile memory storage device of claim 10 , the packet comprises a command packet.
18. The non-volatile memory storage device of claim 10 , the memory elements comprising NAND flash memory devices or phase change memory devices.
19. A method comprising:
detecting, at a host, a trigger to communicate a timestamp;
generating a command packet that includes the timestamp;
flagging the command packet to indicate that the command packet includes the timestamp;
identifying a non-volatile memory storage device coupled with the host to receive the command packet; and
causing the command packet to be sent to the non-volatile memory storage device for the non-volatile memory storage device to determine a time during which the non-volatile memory storage device has been in a powered-down state and use the determined time to calculate a remaining useful life of memory elements included in the non-volatile memory storage device.
20. The method of claim 19 , the trigger comprising a power-on event or a power-down event.
21. The method of claim 19 , the powered-down state comprising a powered off state, a hibernation state, a standby mode or otherwise idled state.
22. The method of claim 19 , the timestamp comprising a time delta.
23. The method of claim 19 , comprising:
allocating a protected location in the non-volatile memory storage device;
and causing the timestamp to be stored to the protected location.
24. The method of claim 23 , comprising:
causing the timestamp to be stored in the protected location using a log page.
25. At least one non-transitory machine readable medium comprising a plurality of instructions that in response to being executed by a host of a computing platform, cause the host to:
detect a trigger to communicate a timestamp;
generate a command packet that includes the timestamp;
flag the command packet to indicate that the command packet includes the timestamp;
identify a non-volatile memory storage device coupled with the host to receive the command packet; and
cause the command packet to be sent to the non-volatile memory storage device for the non-volatile memory storage device to determine a time during which the non-volatile memory storage device has been in a powered-down state and use the determined time to calculate a remaining useful life of memory elements included in the non-volatile memory storage device.
26. The at least one non-transitory machine readable medium of claim 25 , the trigger comprising a power-on event or a power-down event.
27. The at least one non-transitory machine readable medium of claim 25 , the powered-down state comprising a powered-off state, a hibernation state, a standby mode or otherwise idled state.
28. The at least one non-transitory machine readable medium of claim 25 , the timestamp comprising a time delta.
29. The at least one non-transitory machine readable medium of claim 25 , comprising the instructions to further cause the host to:
allocate a protected location in the non-volatile memory storage device;
and cause the timestamp to be stored to the protected location.
30. The at least one non-transitory machine readable medium of claim 29 , comprising the instructions to further cause the host to:
cause the timestamp to be stored in the protected location using a log page.
