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 analog current from each respective die that corresponds to the power consumption of each respective die. The technique further provides for driving each respective analog current onto a common node that results in a cumulative analog current; and utilizing the cumulative analog current at the common node to indicate 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 analog current from each respective die that corresponds to the power consumption of each respective die;
- driving each respective analog current onto a common node, resulting in a cumulative analog current;
- and
- utilizing the cumulative analog current at the common node 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, are capable of causing 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 analog current from each respective die that corresponds to the power consumption of each respective die;
- driving each respective analog current onto a common node, resulting in a cumulative analog current;
- and
- utilizing the cumulative analog current at the common node to indicate total power consumption of the plurality of dice.
A system comprising:
- a processor configured to operate with a plurality of non-volatile memory components;
- and
- a package containing a plurality of dice, in which each die of the plurality of dice contains one or more non-volatile memory component of the plurality of non-volatile memory components, wherein each die includes a power management logic to:
- determine power consumption for operating each respective die;
- generate a respective analog current that corresponds to the power consumption of the die;
- and
- drive the respective analog current onto a common node;
- wherein a cumulative analog current at the common node to indicate total power consumption of the plurality of dice.
