Abstract
A dual-ported AND-type match-line circuit includes at least one dual-ported dynamic AND gate. The dual-ported dynamic AND gate includes a group of CAM cells and a dual-ported dynamic circuit. A group of CAM cells connected to a dual-ported dynamic circuit and to the GND. The dual-ported dynamic circuit is connected to a group of CAM cells. The dual-ported dynamic circuit includes a setting circuit, a first directing circuit, a second directing circuit, a first AND dynamic output circuit and a second AND dynamic output circuit.
