Abstract:
An example ternary content addressable memory. A bit cell of the memory may include a first memristor that has a first terminal that is connected to a first data line and a second terminal that is selectively connected to a second data line via a first switching transistor. The bit cell may also include a second memristor that has a first terminal that is connected to a third data line and a second terminal that is selectively connected to a fourth data line via a second switching transistor. The bit cell may also include a first match-line transistor and a second match-line transistor that are connected in series between a first rail and a match line, with a gate of the first match-line transistor being connected to the second terminal of the first memristor, and a gate of the second match-line transistor being connected to the second terminal of the second memristor.
