  • Memory refresh rate throttling for saving idle power
    Patent number: 9116699
    Abstract: A computer system maintains a threshold value, wherein the threshold value indicates a period of time. The computer system determines that a processor is in any one of a plurality of low power consumption states. Responsive to a determination that the processor is in any one of the plurality of low power consumption states, the computer system increments a counter. The counter indicates the period of time the processor has been in any one of the plurality of low power consumption state. The computing system determines that the counter value is equal to or greater than the threshold value. Responsive to a determination that the counter value is equal to or greater than the threshold value, the computer system sends a first indication to a memory module indicating to the memory module to reduce the memory module refresh rate.
