ABSTRACT:
A tree-style AND-type match circuit device applied to the content addressable memory (CAM) is provided. In this tree-style AND-type match circuit device, a plurality of AND-type match circuit groups branchingly connect with each other by a first AND logic gate. The tree-style AND-type match circuit increases the parallelism of the evaluation of the entire match circuit so that it can efficiently reduce the searching period and the switching activity. Thus, the switching caused by the transformation activity is also shortened. As a result, the match circuit device will not increase the loading of the clock signal so the power consumption is reduced significantly.
