An apparatus and method is disclosed for a CAM priority match detection circuit which determines a "near match" condition using a current-based decoder. The decoder uses n input lines and m complement lines to generate 2<n >outputs, where the 2n outputs form a priority code for a given CAM word. The priority match detection circuit determines which CAM word or words out of a plurality of CAM words has the least amount of mismatching bits and prioritizes the CAM word or words in accordance with such determination.
