Abstract
Comparator circuitry and a method of operation are provided. First and second match lines are precharged. First and second information are compared, and the first match line is selectively discharged in response thereto. Third and fourth information are compared, and the second match line is selectively discharged in response thereto. The second match line is discharged in response to discharging the first match line.
