Abstract
A CAM cell array ( ) that can provide a longest prefix matching operation without necessarily requiring data values to be stored in a particular order. A comparand value can be applied to a CAM cell array ( ) to generate ternary match indications. The mask/prefix data values of ternary match indications can be combined to generate a longest prefix value. The longest prefix value can be compared with the mask/prefix data values of the ternary match indications to indicate a data value having a longest prefix match with the comparand value.
