ABSTRACT:
A circuit for detecting multiple address matches in an associative array includes a match current generator that responds to active match signals generated by the associative array by generating a match current that is linearly proportional to the number of active match signals generated by the array. A reference current source generates a reference current that is between one and two times greater than the match current when a single active match signal is generated by the associative array. A comparator compares the match current and the reference current and generates an active output signal when the match current is greater than the reference current.
