Abstract
A content addressable memory (CAM) device (100) may include a number of blocks (102-[n−1, n, n+1]) that each generate CAM search results and result compare circuits (104-[n−1, n, n+1] that receive CAM search results from multiple blocks (102-[n−1, n, n−1]), and compare at least a portion of such CAM search results. According to such a comparison result, a compare circuit (104-[n−1, n, n+1]) can generate an output CAM search result for subsequent comparison with CAM search result in another compare circuit (104-[n−1, n, n+1]).
