Abstract
Methods, systems, and apparatuses include determining, by a memory subsystem, use model statistics for a memory portion of the memory subsystem, where the use model statistics include a count of commands received by the memory subsystem from a host system targeting the memory portion and details about the memory subsystem. It is determined that the memory subsystem is powering down. The use model statistics are stored in a use model statistics storage of the memory subsystem by the memory subsystem in response to determining that the memory subsystem is powering down.
Claims20
A method comprising:
- determining, by a controller of a memory subsystem, use model statistics for a memory portion of the memory subsystem, wherein the use model statistics include a number of commands received by the controller of the memory subsystem from a host system targeting the memory portion and details about the memory subsystem;
- determining that the memory subsystem is powering down;
- and
- storing, by the memory subsystem, in response to determining that the memory subsystem is powering down, the use model statistics in a use model statistics storage of the memory subsystem, wherein the use model statistics storage includes memory portions accessible by the host system.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
- determine, by a controller of a memory subsystem, use model statistics for a memory portion of the memory subsystem, wherein the use model statistics include a number of commands received by the controller of the memory subsystem from a host system targeting the memory portion and details about the memory subsystem;
- determine that the memory subsystem is powering down;
- and
- store, by the memory subsystem, in response to determining that the memory subsystem is powering down, the use model statistics in a use model statistics storage of the memory subsystem, wherein the use model statistics storage includes memory portions accessible by the host system.
A system comprising:
- a plurality of memory devices;
- and
- a processing device, operatively coupled with the plurality of memory devices, to:
- determine, at power up of a memory subsystem, a next free memory subportion of a use model statistics storage, wherein storing the use model statistics comprises storing the use model statistics in the next free memory subportion;
- determine, by a controller of the memory subsystem, use model statistics for a memory portion of the memory subsystem, wherein the use model statistics include a number of commands received by the controller of the memory subsystem from a host system targeting the memory portion and details about the memory subsystem;
- determine that the memory subsystem is powering down;
- and
- store, by the memory subsystem, in response to determining that the memory subsystem is powering down, the use model statistics in the use model statistics storage of the memory subsystem, wherein the use model statistics storage includes memory portions accessible by the host system.
