Abstract
According to one embodiment, a content addressable memory (CAM) ( ) can include a number of ordinary rows ( - to -n) that provide ordinary match indications (Match to Matchn) as well as redundant rows ( - and - ) that can provide redundant match indications (RMatch and RMatch ). If an ordinary row ( - to -n) is defective, a redundancy multiplexer ( - to -n) can be switched to provide a redundant match indication (RMatch and RMatch ) as an input to a priority encoder ( ) instead of the ordinary match indication from the defective ordinary row.
