ABSTRACT:
A frame buffer designed to allow frame buffer operations which do not involve new row addresses to be accomplished without the need for a RAS cycle. The elimination of RAS cycles for address loading and similar functions substantially accelerates the operation of the frame buffer both as to functions which do not involve memory array addresses and those which do involve memory array addresses.
