Abstract
Method and apparatus for using one bit per line of system memory to maintain coherency in a dual-ported memory system. The states of the bit are "Owned" and "Unowned." The state of the bit is used to filter the number of cycles required to maintain coherency. The bits are stored within the system memory.
