Abstract
A method includes detecting a trigger condition, and in response to detecting the trigger condition, reducing a voltage applied to a graphics controller component of a memory controller. The reduction in voltage may cause the voltage to be reduced below a voltage level required to maintain context information in the graphics controller component.
Claims25
A method comprising:
- detecting a trigger condition;
- in response to detecting the trigger condition, reducing a voltage applied to a graphics controller component of a memory controller, said reducing causing the voltage to be reduced below a voltage level required to maintain context information in said graphics controller component.
An apparatus comprising a memory controller, the memory controller including a graphics controller component, and the memory controller also including a power management controller for controlling a supply of power for at least a portion of the memory controller, the power management controller operative to:
- detect a trigger condition;
- in response to detecting the trigger condition, reduce a voltage applied to the graphics controller component of the memory controller, said reduction causing the voltage to be reduced below a voltage level required to maintain context information in said graphics controller component.
A system comprising:
- a memory controller;
- and
- a graphics memory unit in communication with the memory controller;
- wherein the memory controller includes a graphics controller component, and the memory controller also includes a power management controller for controlling a supply of power for at least a portion of the memory controller, the power management controller operative to:
- detect a trigger condition;
- in response to detecting the trigger condition, reduce a voltage applied to the graphics controller component of the memory controller, said reduction causing the voltage to be reduced below a voltage level required to maintain context information in said graphics controller component.
