A method and apparatus for sharing the video memory of a graphic chip includes the steps as follows: when the destination block of a frame buffer executes color expansion, storing a color LUT to a memory shared by both pattern and color LUT in a video memory, so as to provide color expansion; and when the graphic engine accesses a pattern memory, storing a pattern block to the memory shared by both pattern and color LUT for the access of a graphic engine. By the above-mentioned sharing mechanism, the physical layout area of the graphic chip is reduced and the cost also drops.
