Abstract
Quaternary CAM cells are provided that include a compare circuit having a discharge path between a match line and ground potential, the single discharge path consisting essentially of a single transistor. In an embodiment, the single transistor has a gate coupled to a pull-down node and the compare circuit includes first and second gating transistors connected in series between the pull-down node and a ground potential, the first gating transistor having a gate to receive a comparand bit, and the second gating transistor having a gate to receive a complemented comparand bit.
