Abstract
A content addressable memory (CAM) () is disclosed that includes a value match mode, where a comparand value can be compared to a masked data value, and a range match mode where a comparand value can be compared to an upper range limit UR and a lower range limit LR. The CAM () may include a number of CAM cells (-to-) that may each be connected to a compare section (). A compare section () can include a first compare circuit () that may generate a match indication on a match line () and a second compare circuits (-to-). A more significant second compare circuits (-) may provide upper and lower limit match results (UMn, LMn) to a less significant first compare circuit ().
