An example content addressable memory. A bit cell of the memory may include a memristor and a switching transistor that are connected in series between a first data line and a second data line. The bit cell may also include a match-line transistor connected between a match line and a rail. A gate of the match-line transistor may be connected to a common node of the memristor and the switching transistor. The switching transistor may be sized such that its channel resistance when on is between a resistance associated with a low-resistance state of the memristor and a resistance associated with a high-resistance state of the memristor.
