Abstract

A ternary content addressable memory (TCAM) is disclosed. The TCAM includes a memory array, a data match module, and compare circuitry. The memory array stores a data entry for a data word and a corresponding duplicate data entry for the data word. The data match module compares the data entry to an input word to produce a first match output, and compares the duplicate data entry to the input word to produce a second match output. The compare circuitry compares the first match output and the second match output.
