1. A memory device, comprising:

a memory array; and

circuitry configured to:

determine one or more settings for the memory array corresponding to a powered-on state of the memory device;

communicate the one or more settings to a connected host device;

store the one or more settings in a non-volatile memory location; and

in response to returning to the powered-on state from a reduced-power state, read the one or more settings from the non-volatile memory location.

2. The memory device of claim 1 , wherein the circuitry is further configured, in response to returning to the powered-on state from the reduced-power state, to read the one or more settings from the non-volatile memory location without re-determining the one or more settings.

3. The memory device of claim 1 , wherein the one or more settings include a read timing setting, a write timing setting, a CMD/CTL/ADDR timing setting, an ODT setting, a voltage setting, a latency setting, a ZQ calibration, an RCOMP resistance, or a combination thereof.

4. The memory device of claim 1 , wherein the circuitry is configured to determine the one or more settings for the memory array in response to receiving a command from the connected host device.

5. The memory device of claim 4 , wherein the circuitry is configured to communicate the one or more settings to the connected host device in response to the command.

6. The memory device of claim 1 , wherein the circuitry is configured to determine the one or more settings for the memory array in response to entering the powered-on state from a powered-off state.

7. The memory device of claim 1 , wherein the circuitry is further configured to cause the memory device to enter the reduced-power state in response to receiving a command from the connected host device.

8. The memory device of claim 1 , wherein the circuitry is further configured to cause the memory device to enter the reduced-power state in response to a determination that the memory device is idle.

9. The memory device of claim 1 , wherein the circuitry is further configured to cause the memory device to return to the powered-on state from the reduced-power state in response to receiving a command from the connected host device.

10. The memory device of claim 1 , wherein the reduced-power state corresponds to a disconnection of at least a portion of the memory array from an applied voltage.

11. The memory device of claim 1 , wherein the memory array comprises a non-volatile memory.

12. The memory device of claim 11 , wherein the non-volatile memory is one of NAND flash, NOR flash, MRAM, FeRAM or PCM.

13. The memory device of claim 11 , wherein the non-volatile memory comprises the non-volatile memory location.

14. The memory device of claim 1 , wherein a single semiconductor chip comprises the circuitry and the memory array.

15. The memory device of claim 1 , wherein a first semiconductor chip comprises the circuitry and a second one or more semiconductor chips comprise the memory array.

16. A method of operating a memory device including a memory array, the method comprising:

determining one or more settings for the memory array corresponding to a powered-on state of the memory device;

communicating the one or more settings to a connected host device;

storing the one or more settings in a non-volatile memory location; and

in response to returning to the powered-on state from a reduced-power state, reading the one or more settings from the non-volatile memory location.

17. The method of claim 16 , further comprising:

in response to returning to the powered-on state from the reduced-power state, reading the one or more settings from the non-volatile memory location without re-determining the one or more settings.

18. The method of claim 16 , wherein the one or more settings include a read timing setting, a write timing setting, a CMD/CTL/ADDR timing setting, an ODT setting, a voltage setting, a latency setting, a ZQ calibration, an RCOMP resistance, or a combination thereof.

19. The method of claim 16 , wherein determining the one or more settings for the memory array is performed in response to receiving a command from the connected host device.

20. The method of claim 19 ,

wherein the one or more settings are communicated to the connected host device in response to the command.

21. The method of claim 16 , wherein determining the one or more settings for the memory array is performed in response to entering the powered-on state from a powered-off state.

22. The method of claim 16 , further comprising:

entering the reduced-power state in response to a determination that the memory device is idle.

23. The method of claim 22 , further comprising:

returning to the powered-on state from the reduced-power state in response to receiving a command from the connected host device.

24. A memory system, comprising:

a host device; and

a memory device including a memory array operably coupled to the host device, the memory device configured to:

determine one or more settings for the memory array corresponding to a powered-on state of the memory device;

communicate the one or more settings to the host device;

store the one or more settings in a non-volatile memory location; and

in response to returning to the powered-on state from a reduced-power state, read the one or more settings from the non-volatile memory location.

25. The memory system of claim 24 , wherein the memory device is further configured to, in response to returning to the powered-on state from the reduced-power state, communicate the one or more settings to the host device after reading the one or more settings from the non-volatile memory location.
