1. A ternary content addressable memory (TCAM) comprising:
a match line; and
a plurality of TCAM cells connected along the match line, wherein each TCAM cell stores a state of a threshold value, and wherein the TCAM cells are configured to pull down a signal over the match line in response to inequality between an input search and the threshold value,
wherein the plurality of TCAM cells comprises a number of TCAM cells that is less than the threshold value.
