Abstract
The present disclosure includes memory devices and systems having memory cells, as well as methods for operating the memory cells. One or more methods for operating memory cells includes determining age information for a portion of the memory cells and communicating a command set for the portion of the memory cells, the command set including the age information.
Claims21
A method for operating memory cells, comprising:
- determining, by a memory access device, a wear state for the memory cells of a memory device;
- and
- communicating the wear state from the memory access device to the memory device;
- and
- determining, by the memory device, a set of operating parameters for the memory cells in response to the determined wear state.
2 more elements
A memory device, comprising:
- an array of memory cells;
- and
- control circuitry coupled to the array, and adapted to:
- receive a wear state for the memory cells from a memory access device;
- determine at least one operating parameter for the memory cells in response to the received wear state.
2 more elements
A memory system, comprising:
- a memory device including memory cells and control circuitry coupled to the memory cells;
- and
- a memory access device communicatively coupled to the memory device, and adaptable to:
- determine wear cycle information of the memory cells;
- and
- communicate the wear cycle information corresponding to a portion of the memory cells to the memory device when operating the portion of the memory cells,
- wherein the control circuitry is adapted to compensate for memory device performance changes corresponding to the communicated wear cycle information.
