Abstract
A technique to provide power management for multiple dice. The technique provides for determining for each respective die of the multiple dice, power consumption for operating each respective die; and generating a respective signal from each respective die that corresponds to the power consumption of each respective die. The technique further provides for converting each respective signal to a respective analog voltage to drive a common node; and utilizing a charge storage device coupled to the common node to accumulate the respective analog voltages from the dice, where the accumulated voltage indicates total power consumption of the dice.
Claims20
A method comprising:
- determining for each respective die of a plurality of dice, power consumption for operating each respective die;
- generating a respective signal from each respective die that corresponds to the power consumption of each respective die;
- converting each respective signal to a respective analog voltage to drive a common node;
- and
- utilizing a charge storage device coupled to the common node to accumulate the respective analog voltages from the plurality of dice, the accumulated voltage to indicate total power consumption of the plurality of dice.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- determining for each respective die of a plurality of dice, power consumption for operating each respective die;
- generating a respective signal from each respective die that corresponds to the power consumption of each respective die;
- converting each respective signal to a respective analog voltage to drive a common node;
- and
- utilizing a charge storage device coupled to the common node to accumulate the respective analog voltages from the plurality of dice, the accumulated voltage to indicate total power consumption of the plurality of dice.
A system comprising:
- a plurality of dice, in which each die of the plurality of dice contains one or more non-volatile memory components, wherein each die includes a power management logic to:
- determine power consumption for operating each respective die;
- generate a respective signal that corresponds to the power consumption of the die;
- and
- convert the respective signal to a respective analog voltage to drive a common node;
- and
- a charge storage device coupled to the common node that accumulates the respective analog voltages from the plurality of dice, the accumulated voltage indicating total power consumption of the plurality of dice.
