ABSTRACT:
A content addressable memory (CAM) device includes an array having a number N of CAM rows, each row including a plurality of CAM cells coupled to a match line, a spare CAM row including a plurality of CAM cells coupled to a spare match line, and row replacement circuitry configured to functionally replace a defective CAM row and each subsequent CAM row in the array with corresponding next adjacent CAM rows, wherein a last CAM row in the array is functionally replaced by the spare CAM row.
