Abstract:
A ternary content addressable memory (TCAM) cell circuit formed in a TCAM memory cell array having cells arranged in rows and columns can include a first storage circuit with first and second data path, a second storage circuit with a third and fourth data path, and a compare circuit. No more than four conductive lines in a column wise direction have a direct electrical connection to the TCAM cell. Such conductive lines can include a first bit line coupled to the first data path and the third data path and a second bit line coupled to the second data path and the fourth data path.
