A video display controller incorporates an improved half-frame buffer that can be implemented and operated at lower cost. In one implementation, the half-frame buffer incorporates a distribution circuit that receives three serial digital signals conveying bits representing red, green and blue (RGB) colors in an image. The distribution circuit multiplexes the RGB bits into a signal parallel register so that a complete set of RGB information can be written to or retrieved from memory during a single clock cycle. Preferably, the distribution circuit is implemented by simple signal-switching logic.
