Abstract

An integrated circuit (200) includes a semiconductor memory device (202) operative for determining match between received search data and stored data in a plurality of ternary content addressable memory (TCAM) bitcells (100). The plurality of TCAM bitcells (100) each include bit storage including a pair of memory cells (102-0, 102-1) for holding stored data. The TCAM bitcells (100) also include bit comparison circuitry (104) operative for comparing between the stored data and search data on a search line coupled to the TCAM bitcell, wherein the bit comparison circuitry includes a static logic gate operable to provide a match output signal exclusive of a pulsed input. Match circuitry (205) is coupled to receive the match output signal (108) from the plurality of TCAM bitcells (100) for determining whether a match is present for a given search word.
