Abstract:
1. A method for remedying data corruption in a ternary content addressable memory (TCAM) integrated circuit (IC), said TCAM IC having a plurality of word compare circuits, each of said plurality of word compare circuits being configurable to perform either a compare function or a parity checking function during a given cycle of said TCAM IC, comprising: selecting said TCAM IC to perform said one of said compare function and said parity checking function, said compare function and said parity checking function being performed by mutually exclusively shared dual function logic circuitry in said each of said plurality of word compare circuits that performs said compare function and said parity checking function in the alternative in any given cycle of said TCAM IC; if said TCAM IC is selected to perform said compare function, processing outputs of said word compare circuits as TCAM match results; and if said TCAM IC is selected to perform said parity checking function, processing outputs of said word compare circuits as parity error signals.
