ABSTRACT:
A frame buffer operating in fast page access mode with improved performance for operations such as scrolling and moving which typically access different display memory rows. The present invention utilizes a row/bank interleaved scheme of multiple display memory banks in the frame buffer such that each display memory bank supports a different set of non-contiguous display rows thus increasing the odds of display memory access in-page hits and decreasing the odds of display memory access in-page misses.
