Content addressable memory (CAM) device and method for flexible suppression of hit indications

摘要

A content addressable memory (CAM) device (200) can provide for suppression of hit indications. Prioritized match indications (212) can be applied in parallel to both an encoding read-only-memory (ROM) (204-1) and suppression data store (206). A suppression data store (206) can output suppression bits (SH0 and SH1) that correspond to each CAM entry. Hit indications can be selectively suppressed according the values of suppression bits (SH0 and SH1). Hit suppression methods for a CAM device are also disclosed.
