A low-cost high-performance technique for providing bit-mapped graphics display controllers is described whereby video frame buffer memory and video controller functions are integrated together on a single chip, permitting very wide video memory formats without the usual penalties of high pin count, package count, and wiring complexity. The wide video memory format relaxes timing requirements on the video frame buffer memory and provides greater accessibility of the video frame buffer memory for pixel data accesses other than display refresh accesses.
