Abstract:
1. A power management system comprising: a graphic controller configured to generate a first display information signal and a second display information signal; a memory device operatively connected with the graphic controller, a parallel terminal unit, wherein the memory device and the parallel terminal unit are configured to collectively support the graphic controller to generate the first display information signal at a first clock speed and at a first power consumption level, and memory device is configured to support the graphic controller without the parallel terminal unit to generate the second display information signal at a second clock speed and at a second power consumption level; a hybrid cycling controller configured to alternately connect the parallel terminal unit with the memory device for the first display information signal and to disconnect the parallel terminal unit from the memory device for the second display information signal during a predetermined period; and a power consumption controller configured to control the hybrid cycling controller according to a ratio between a connection interval and a disconnection interval of the parallel terminal unit with the memory device, wherein the ratio is set based on a characteristic of a power source operatively connected to the system.
