Abstract
A two-port ternary content addressable memory (TCAM) and layout pattern thereof, and associated memory device are provided. The two-port TCAM may include a first storage unit, a second storage unit, a set of first search terminals, a set of second search terminals, a first comparison circuit, a second comparison circuit, a first match terminal and a second match terminal, wherein the first comparison circuit is respectively coupled to the first storage unit, the second storage unit, the set of first search terminals and the first match terminal, and the second comparison circuit is respectively coupled to the first storage unit, the second storage unit, the set of second search terminals and the second match terminal. First search data and second search data may be concurrently inputted into the two-port TCAM for determining whether the first search data and the second search data match content data within the two-port TCAM.
