Abstract
A collision detection circuit for a multi-port memory system is presented. The collision detection circuit detects a collision condition if the addresses at two or more ports at the same time match and if one of the two or more ports is writing to the memory location associated with that address. A collision flag can then be set when the collision condition exists. In some embodiments, arbitration can occur when the collision flag is set.
