Abstract
A content addressable memory (CAM) includes a number of novel CAM cells that can be switchable between a binary mode of operation and a ternary mode of operation. According to one embodiment, a novel CAM cell (100) can include a switchable impedance path (104) arranged in series with a compare circuit (110). A switchable impedance path (104) can include a first impedance path (106) arranged in series with a second impedance path (108). The first impedance path (106) can be controlled by a mode value (MODE) and the second impedance path (108) can be controlled by a mask value (/M).
