Methods and circuits for CAM cells using PMCs are disclosed herein. In one embodiment, a BCAM cell can include: (i) a first PMC coupled to a first access transistor and a bit node, where the first access transistor is coupled to a true bit line; (ii) a second PMC cell coupled to a second access transistor and the bit node, where the second access transistor is coupled to a complement bit line, and the first and second access transistors are controllable by a word line; (iii) a program enable transistor coupled to the bit node, and configured to couple a program control voltage to the bit node when enabled; and (iv) a match indication transistor configured to discharge a match line in response to states of the true and complement bit lines relative to the bit node.
