Memory sub-system signature generation
A method includes receiving signaling indicative of performance of a shutdown operation involving a memory device to a controller resident on the memory device; initiating a power off sequence in response to the received signaling, wherein the power off sequence includes execution of instructions corresponding to a plurality of routines; and writing data comprising respective shutdown signatures associated with execution of the plurality of routines to a media associated with the memory device upon completion of each of one or more of the plurality of routines, wherein the media is bit-addressable or byte-addressable.
1. A method, comprising:
initiating a sequence in response to a signal indicative of performance of a shutdown operation, wherein the sequence includes execution of instructions corresponding to a plurality of routines;
writing data comprising respective shutdown signatures associated with execution of the plurality of routines to a media upon completion of each of one or more of the plurality of routines, wherein the media is bit-addressable or byte-addressable;
upon a failed completion of one of the plurality of routines, abstaining from writing data comprising a respective shutdown signature associated with the execution of the plurality of routines to the media, and performing a locking operation.
2. The method of claim 1 , further comprising accessing the media to determine which of the plurality of routines have been completed.
3. The method of claim 1 , wherein the signaling corresponds to an asynchronous power loss.
4. The method of claim 1 , wherein the media is a non-volatile media on an enterprise computing device.
5. An apparatus, comprising:
a memory device; and
a controller coupled to the memory device and configured to:
initiate a sequence in response to a signal indicative of performance of a shutdown operation, wherein the sequence includes a plurality of routines; and
write a respective shutdown signature to a media upon completion of each of one or more of the plurality of routines, wherein the respective shutdown signature comprises a respective indicator for each of a number of subroutines, wherein the respective indicator corresponds to completion of execution of each of the number of subroutines.
6. The apparatus of claim 5 , wherein the media is bit-addressable or byte-addressable.
7. The apparatus of claim 5 , wherein the controller is configured to abstain from writing a respective shutdown signature to the media upon a failed completion of one of the plurality of routines.
8. The apparatus of claim 5 , wherein the memory sub-system comprises a solid-state drive.
9. The apparatus of claim 5 , wherein the controller is configured to write the respective shutdown signature that meet a threshold energy consumption criteria.
10. The apparatus of claim 5 , wherein the apparatus comprises an enterprise system and includes a stackable cross-gridded array of memory cells.
11. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
initiate a sequence in response to a signal indicative of performance of a shutdown operation, wherein the power off sequence includes a plurality of routines;
store a respective shutdown signature to a media upon completion of each of one or more of the plurality of routines; and
abort the sequence when one of the plurality of routines is not completed.
12. The medium of claim 11 , wherein the respective shutdown signature is stored at a portion of the non-volatile media that is reserved for shutdown signatures.
13. The medium of claim 12 , wherein respective shutdown signatures are stored sequentially at the portion of the media that is reserved for shutdown signatures.
14. The medium of claim 11 , wherein aborting the sequence when one of the plurality of routines is not completed further comprises not locking one or more of a plurality of memory components.
15. The medium of claim 11 , wherein aborting the sequence when one of the plurality of routines is not completed comprises aborting the sequence when a subroutine of one of the plurality of routines is not completed.
16. The medium of claim 11 , wherein the media is non-volatile and is bit addressable or byte addressable.
