Abstract
A control circuit for a ternary content-addressable memory includes a first logic unit and a second logic unit. The first logic unit is coupled to a first storage unit, a second storage unit, a first search line, a second search line, a reference voltage terminal, and a match line. The second logic unit is coupled to the first storage unit, the second storage unit, the first search line, the second search line, a first power supply line and a second power supply line. When voltages at the first search line and the second search line match voltages at the first storage unit and the second storage unit, the second logic unit provides a path for electrically connecting the first power supply line to the second power supply line.
