According to one embodiment, a content addressable memory (CAM) device ( 100 ) may include a number of segments ( 102 or 104 ). Search target compare circuits ( 110 and 112 ) can compare a target value TARGET to programmable information values (PIV 0 and PIV 1 ) associated with a particular segment ( 102 and 104 ). If a search target value TARGET matches a programmable information value (PIV 0 and PIV 1 ), search operations may be performed in a segment ( 102 or 104 ). If a search target value TARGET does not match a programmable information value, (PIV 0 and PIV 1 ), search operations may be prevented within a segment ( 102 or 104 ).
