摘要：
A content addressable memory (CAM) (100) can include a number of CAM entries (102-0 to 102-n). Match indications from CAM entries (102-0 to 102-n) and mismatch indications from complementing circuits (106-0 and 106-n) can be supplied to a switching circuit (108). Mismatch indications can indicate if an entry mismatches data when compared with a comparand (104). In one mode of operation, a switching circuit (108) can provide match indications on a number of switch outputs (SW0 to SWn). In another mode of operation, switching circuit (108) can provide mismatch indications on a number of switch outputs (SW0 to SWn).
