ABSTRACT:
A method and apparatus for performing fly-by transfer in a memory subsystem of a computer system. The present invention transfers data between a display memory and the system memory in the memory subsystem using common data and address buses. To complete a transfer between the two, the RAS is activated for both the display and system memory banks and then the CAS signal is cycled for both the display memory and the system memory, thereby causing a page mode transfer of the data between the two memories without having to use the system bus of the computer system.
