Abstract
The plurality of CAM cells MC are configured to discriminate a match or mismatch between stored data stored in advance and search data. A match line is coupled to a plurality of CAM cells, and has a voltage level controlled based on discrimination results of the plurality of CAM cells. A first transistor and a second transistor are coupled in series between a common match output line and a predetermined power source. The first transistor is controlled to be turned ON or OFF based on a voltage level of the match line, and the second transistor is controlled to be turned ON or OFF by a search enabling signal asserted at the time of a search operation.
