Abstract
In an example, an apparatus may include a memory comprising a number of groups of memory cells and a controller coupled to the memory and configured to track respective invalidation velocities of the number of groups of memory cells and to assign categories to the number of groups of memory cells based on the invalidation velocities.
Claims28
An apparatus, comprising:
- a memory comprising a plurality of groups of memory cells;
- and
- a controller coupled to the memory and configured to:

3 more elements
An apparatus, comprising:
- a plurality of groups of memory cells;
- a processing device coupled to the plurality of groups of memory cells, the processing device configured to:
- track a respective timewise variation of a number of valid portions of each respective group of memory cells;
- and
- perform an operation on the respective groups of memory cells based on the respective timewise variation of the number of valid portions of the respective groups of memory cells.
2 more elements
A method, comprising:
- tracking respective data invalidation velocities for a plurality of logical address ranges corresponding to groups of memory cells in a memory;
- and
