Abstract
Briefly, in accordance with one embodiment of the invention, an integrated circuit has a voltage regulator that is used to provide a power supply potential to a memory circuit while a logic circuit is decoupled from a power supply potential.
Claims18
An apparatus having an integrated circuit, the integrated circuit comprising;
- a first circuit having a power supply potential and adapted to store a volatile logic value;
- and
- a second circuit adapted to generate a logic value when coupled to receive the power supply potential from the first circuit in a first operational mode and decoupled from receiving the power supply potential when the first circuit is not in the first operational mode.
A method comprising:
- supplying a power supply voltage potential to a memory circuit;
- coupling the power supply voltage potential from the memory circuit to a logic circuit when an integrated circuit is in a first operational mode;
- and
- retaining a volatile logic value in the memory circuit while decoupling the power supply voltage potential from the logic circuit when the integrated circuit is in a second operational mode.

A computing system comprising:
- a static random access memory;
- and
- an instruction processing unit, the instruction processing unit comprising:
- a first circuit to receive a power supply potential and store a volatile logic value;
- and
- a second circuit coupled to the first circuit to receive the power supply potential in a first operational mode and generate a logic value, wherein the instruction processing unit decouples the power supply potential from at least a portion of the second circuit in a second operational mode and the first circuit retains the volatile logic value.
