ABSTRACT:
A method for avoiding a tag duplicate fault. The method includes the steps of using a master - slave tag; selecting a first tag as a master and a second tag as a slave; inhibiting the second tag from initiating a hit signal when the first tag is set for a hit condition, and enabling the second tag to initiate a bit signal when the first tag is set for a miss condition.
