Content addressable memory

摘要

Systems and methods are provided for searching at least one content addressable memory entry associated with a content addressable memory (CAM). A given content addressable memory entry comprises a plurality of CAM fields. At least one input selector controls access to the plurality of CAM fields, such that retrieval of a subset of the plurality of CAM fields is selectively enabled. A match evaluator compares an enabled subset of CAM fields to a search value.
