Abstract: An integrated circuit device includes a semiconductor substrate and an array of random access memory (RAM) cells, which are arranged on the substrate in first columns and are configured to store data. A computational section in the device includes associative memory cells, which are arranged on the substrate in second columns, which are aligned with respective first columns of the RAM cells and are in communication with the respective first columns so as to receive the data from the array of the RAM cells and to perform an associative computation on the data.

Abstract: An associative processor includes a plurality of arrays of content addressable memory (CAM) cells and a plurality of tags registers in a tags logic block. Different tags registers are associated with different CAM cell arrays at will, to support parallel execution of the same or different arithmetical operations on two or more CAM cell arrays, and to support pipelined arithmetical operations by having two CAM cell arrays share a tags register to transfer data from one CAM cell array to another using appropriate compare and write operations. All the CAM cell arrays share the same mask and pattern registers. Preferably, at least one tags register is located physically between two of the CAM cell arrays.
