Abstract
Apparatus, system and method for managing power of a main circuitry disposed on a main substrate using a control circuitry disposed on a control substrate, in a stacked relationship with the main substrate, are described herein.
Claims27
An apparatus, comprising:
- a main substrate;
- a main circuitry formed on the main substrate;
- a control substrate stacked with the main substrate;
- and
- a control circuitry formed on the control substrate, electrically coupled to the main circuitry, and adapted to perform power management for at least a portion of the main circuitry.
2 more elements
A system, comprising:
- a processor circuitry formed on a main substrate;
- a memory electrically coupled to the processor circuitry;
- a control substrate stacked with the main substrate;
- a control circuitry formed on the control substrate and electrically coupled to the processor circuitry, the control circuitry is adapted to perform power management of at least a portion of the processor circuitry;
- and
- a data storage device coupled to both the processor circuitry and the memory for providing persistent mass data memory.
3 more elements
A method, comprising:
- providing a main substrate;
- forming a main circuitry on the main substrate;
- providing a control substrate;
- forming a control circuitry on the control substrate, the control circuitry being adapted to perform power management for at least a portion of the main circuitry;
- and
- stacking the main substrate and the control substrate, including electrically coupling the control circuitry to the main circuitry for the performance of power management.
3 more elements
A method comprising:
- receiving power by a control circuitry disposed on a control substrate;
- and
- conditionally allowing the received power to be provided through the control circuitry to at least a portion of a main circuitry disposed on a main substrate stacked with the control substrate.
