  • Ternary content addressable memory with enhanced priority matching
    Patent number: 6996664
    Abstract: The disclosed system and method describe a ternary CAM device having, in addition to a data entry and a ternary mask entry, one or more additional control words which can specify a net mask length and status, a table identifier, and/or a validity word to specify a detailed status of the segmented data words stored. This allows for the matching of ternary CAM device entries with a comparand without sorting ternary CAM device entries. Additional status words can be used for table identification to save space in the actual data word entries, and also allowing for matching of data entries with selected table identifiers, precluding having to search the entire ternary CAM array. Additional status words can also be used to provide additional state information to provide more flexibility in validity checking. The disclosed system and method can be used in ternary CAM devices having and/or supporting varying word widths.
