Nimbus: An integrated display chip

Abstract

With SRAM technology delivering more than a million bits per chip, it is now feasible to integrate display memory with display control. The circuit described contains a two-port SRAM array, one port being serial access combined with duty cycle modulation for gray-scale display on LCDs. The memory array itself is synchronous with the processor port, providing low-latency, high-bandwidth access for image manipulation.<>
