US Patent 7106619 Graphics controller integrated circuit without memory interface

A graphics controller system which has a graphics engine and video memory together with some interface blocks, a PCMCIA host adapter, an infrared interface for generating video images on a LCD or CRT display unit, and a video stream interface for receiving video signals, all in the form of a CMOS integrated circuit. The video memory is integrated on the same integrated circuit as the graphics controller; no package pins are required for the memory interface. Simultaneous performance improvement and power dissipation reduction is achieved because of the wide memory interface and the elimination of the large parasitic capacitances associated with a package pin connection.
