A method and structure for content addressable memory structure having a memory array of words, each word having multiple memory bits and a plurality of matchlines. Each of the matchlines is connected to one of the words and a matchline compare circuit is connected to the matchlines and is adapted to test all of the words individually. The matchline compare circuit includes a plurality of comparators equal in number to a number of the words, such that each word is connected to a dedicated comparator to allow each word in the memory array to be individually tested.
