Abstract:
A content-addressable memory (CAM) with computational capability is described. The CAM includes an array of CAM cells arranged in rows and columns with a pair of search lines associated with each column of the array and a match line associated with each row of the array. The array of CAM cells is configured to implement, for a given cycle, either a read operation of data contained in a single selected column, or one of a plurality of different bitwise logical operations on data contained in multiple selected columns. All of the pairs of search lines in the columns of the array are configured to a certain state to implement the read operation or one of the plurality of different bitwise logical operations. A result of the read operation or one of the plurality of different bitwise logical operations is outputted onto all of the match lines in the array.
