Patent ID: 7433217

Claim:
A configurable content addressable memory (CAM) cell circuit, comprising: a compare section that selectively enables at least one discharge path in response to at least first and second compare inputs; a configuration section comprising a first transistor having a controllable impedance path coupled between a first line and the first compare input, and a second transistor having a controllable impedance path coupled between a second line and the second compare input; a first storage circuit having a first storage node coupled to a control terminal of the first transistor and a third transistor having a controllable impedance path coupled between the first line and the first storage node and a control terminal coupled to a first word line; and a second storage circuit having a second storage node coupled to a control terminal of the second transistor and a fourth transistor having a controllable impedance path coupled between the second line and the second storage node and a control terminal coupled to a second word line.
