ABSTRACT:
A content addressable memory (CAM) device includes a CAM array, a programmable interconnect structure, and a priority encoder. The CAM array includes a plurality of CAM rows, each row including a number of CAM cells for storing a data word and coupled to a match line that indicates a match result for the CAM row. The programmable interconnect structure is coupled to each CAM row and a plurality of CAM rows, each row including a number of CAM cells for storing a data word and coupled to a match line that indicates match results for the row. The programmable interconnect structure coupled to each CAM row, and is configured to logically connect any number N of selected CAM rows together to form a data word chain spanning N rows, regardless of whether the selected CAM rows are contiguous.
