System And Method For Storing Manufacturing Information And Lifetime Usage History Of A Power Module For A Memory System
A memory system is described. The memory system includes a plurality of memory subsystems. Further, the memory system includes a controller coupled with the plurality of memory subsystems. The memory system also includes a power module including a storage device configured to store information and the power module is detachably coupled with the controller.
1 . A memory system comprising:
one or more memory subsystems;
a controller coupled with said one or more memory subsystems;
a power module coupled with the memory system and including a storage device configured to store information relating to said power module.
2 . The memory system of claim 1 , wherein said storage device includes a non-volatile memory device.
3 . The memory system of claim 1 , wherein said power module is configured to be detached from said memory system.
4 . The memory system of claim 1 , wherein said storage device is configured to store information including manufacturing information of said power module.
5 . The memory system of claim 1 , wherein said storage device is configured to store lifetime usage history of said power module.
6 . The memory system of claim 5 , wherein at least a first one of said one or more memory subsystems includes non-volatile memory.
7 . The memory system of claim 6 , wherein at least a second one of said one or more memory subsystems includes volatile memory.
8 . The memory system of claim 7 , wherein said controller is configured to control a transfer of information from said volatile memory to said non-volatile memory.
9 . The memory system of claim 5 , wherein said lifetime usage history of said power module includes one or more measured usage/lifetime values of said power module.
10 . The memory system of claim 9 , wherein said controller is configured to update at least one of said one or more measured usage/lifetime values.
11 . A method to store information in a storage device of a power module, the method comprising:
receiving first information to store in said storage device located on said power module;
storing said first information in said storage device located on said power module.
12 . The method of claim 11 , wherein said first information includes manufacturing information of said power module.
13 . The method of claim 11 , further comprising:
receiving at said storage device a command from a controller; and
transmitting said first information to said controller in response to said command.
14 . The method of claim 11 , wherein said first information includes one or more measured usage/lifetime values.
15 . The method of claim 14 , wherein said one or more measured usage/lifetime values include lifetime usage history of said power module.
16 . The method of claim 14 , further comprising:
generating second information to store in said storage device located on said power module;
transmitting said second information to said storage device; and
storing said second information in said storage device, wherein said second information includes an update to said one or more measured usage/lifetime values.
17 . The method of claim 16 , wherein generating said second information is performed by a controller of a memory system including one or more memory subsystems.
18 . The method of claim 16 , wherein generating said second information to store in said storage device located on said power module is in response to a determination that a value passed a threshold.
19 . The method of claim 16 , wherein generating said second information to store on said storage device located on said power module is in response to a determination that a successful backup has occurred.
20 . The method of claim 16 , wherein generating said second information to store on said storage device located on said power module is in response to a determination that a value has exceeded a percentage of change from a last stored value.
21 . The method of claim 16 , wherein said first information or said second information includes a command from said controller.
22 . The method of claim 21 further comprising updating said first information or said second information in said storage device located on said power module in response to said command.
23 . A power module for a memory system including a plurality of memory subsystems comprising:
means for receiving information to store on a storage device located on said power module;
means for storing said information in said storage device located on said power module; and
means for transmitting said information to a controller.
