Abstract
A content addressable memory that may have reduced charge consumption when switching compare lines is disclosed. According to one embodiment, a content addressable memory (CAM) ( ) with paired compare lines (CMP and CMP\) can include an equalization circuit ( ) between the two compare lines (CMP and CMP\). An equalization circuit ( ) can enter a low-impedance mode when an equalization control signal (EQU\) is in one state and enter a high-impedance mode when an equalization control signal (EQU\) is in another state. An equalization control signal (EQU\) may be governed by an output pulse of a transition detector ( ).
