A new CAM macro for 622 Mbps ATM cell processing

A CAM macro for 622 Mbps ATM cell processing has been developed with two built-in circuits, the idle word detection circuit and the multiple hit detection circuit. The macro is fabricated in a standard 0.5 /spl mu/m 3 layer CMOS technology, 40 MHz operation and 70 mW power dissipation with 3.3 V power supply has been confirmed.
