A content addressable memory (CAM) device has an array including a plurality of CAM rows that are partitioned into row segments, wherein a respective row includes a first row segment including a number of first CAM cells coupled to a first match line segment, a second row segment including a number of second CAM cells coupled to a second match line segment, and a circuit to selectively pre-charge the first match line segment in response to a value indicating whether data stored in the first row segment of the respective row is the same as data stored in the first row segment of another row. Power consumption can be reduced during compare operations in which the first row segment of another row that stores the same data as the first row segment of the respective row is not enabled.
