1. A method comprising:

  • determining that a memory device is in an inactive state; and

    in response to determining that the memory device is in the inactive state, determining whether a power consumption of the memory device may be reduced based, at least in part, on a temperature of the memory device, including;

    in response to determining the temperature of the memory device is below a temperature threshold, communicating with a voltage regulator coupled with the memory device to reduce a supply voltage output to the memory device, wherein the reduced supply voltage is set between a first voltage level and a second voltage level, the second voltage level being higher than the first voltage level, wherein the memory device fails if the supply voltage is set below the first voltage level when the temperature of the memory device is below the temperature threshold, and wherein the second voltage level is a memory device manufacturer specified minimum level of the supply voltage required to operate the memory device correctly for all memory states; and

    in response to determining the temperature of the memory device is above the temperature threshold, maintaining the supply voltage output to the memory device.
