Abstract
A content addressable memory (CAM) device includes an array of memory cells arranged in rows and columns; compare circuitry configured to indicate match results of search data presented to each row of the array; and compare circuitry configured to indicate match results of search data presented to each column of the array, thereby resulting in a two-dimensional search capability of the array.
