A graphics display controller providing enhanced read/write efficiency for interfacing with a RAM-integrated graphics display device. According to the invention, a graphics display controller is disclosed for interfacing between a host and a graphics display device having an associated memory is provided that includes an embedded memory, a format converter, and a data storage memory. The embedded memory is adapted for storing frames of video data received from a host. The format converter is adapted to convert the video data in at least one of two ways: (1) from the data format of the host to the data format of the display device and (2) from the data format of the display device to the data format of the host. The data storage memory has a memory size that is smaller than the embedded memory, and defines a data path that bypasses the embedded memory but connects to the format converter.
