Abstract:
1. A content addressable memory (CAM) device comprising: a CAM array to store data words, compare the data words with a comparand value, and output a match signal that corresponds to a comparand-matching data word of the data words; a priority encoder coupled to receive the match signal from the CAM array and configured to output a match address that corresponds to the comparand-matching data word; an address circuit coupled to receive the match address from the priority encoder and configured to activate a word line that corresponds to a portion of the CAM array containing the comparand-matching data word, the word line, when activated, enabling the comparand-matching data word to be output from the CAM array; and an error detecting circuit coupled to receive the comparand-matching data word from the CAM array and configured to determine whether the comparand-matching data word has an error.
