Apparatus and methods are disclosed for controlling the memory controller and, in particular, controlling signaling of the memory controller to a memory via memory interface during a static screen condition. An apparatus includes static image detection logic that is configured to detect when image data being displayed by a display controller is static and to communication detection of static image data to the display controller. The apparatus also includes control logic within the display controller responsive to the static image detection logic, where the control logic is configured to detect a level of a line buffer within the display controller and to send a signal to a memory controller directing the memory controller to issue a signal to a memory to enter a self-refresh mode, thereby turning off at least one memory clocking circuit within the memory controller. A corresponding method is also disclosed.
