Abstract
A content addressable memory (CAM) device includes a plurality of CAM rows, a number of sequencing logic circuits, and a programmable interconnect structure. Each CAM row includes a number of CAM cells to generate a match signal on a match line and includes an enable input. Each sequencing logic circuit includes an input and an output, and is configured to count sequences of match signals from the CAM rows. The programmable interconnect structure selectively connects the match line of any CAM row to the input of any sequencing logic circuit, and selectively connects the output of any sequencing logic circuit to the enable input of any CAM row.
