Abstract
Computer memory conflict avoidance using a plurality of page registers coupled individually to a plurality of memory banks is described. An incoming system address request containing a requested memory bank number and a requested page number is received by the memory controller. The page register number corresponding to the requested memory bank is located and the open page address in the located page register is compared to the requested page address. If the requested page number corresponds to the open page address, it is then accessed. If it does not match, the memory page corresponding to the requested page address is closed, the memory page corresponding to the requested page address is opened and then accessed.
