Abstract
A method and apparatus are provided for increasing the density and performance of a Content Addressable Memory (CAM). According to one embodiment, the CAM includes a comparison circuit, an enable circuit, and a bias circuit. The comparison circuit compares a stored bit to an input bit and outputs an inverted result of the comparison. The enable circuit receives as inputs the inverted result of the comparison and an enable input and produces an enabled comparison result. The bias circuit receives the enabled comparison result as its only input and discharges a pull-down line based upon the enabled comparison result.
