Abstract
According to one embodiment, a content addressable memory (CAM) device (100) may include a number of CAM entry sets (102-0 and 102-1), each of which includes multiple CAM entries. CAM (100) may also include multiple programmable information registers (PIRs) (104-0 and 104-1), each of which can be associated with a CAM entry set (102-0 and 102-1). PIRs (104-0 and 104-1) may be accessed in response to CAM commands. Values stores in PIRs (104-0 and 104-1) may control access to associated CAM entry sets (102-0 and 102-1) and/or be output in response to predetermined operations in an associated CAM entry set (102-0 and 102-1).
