Abstract
A content addressable memory (CAM) unit does not have any in-cell comparator circuitry. The CAM unit includes a memory array, a multiple row decoder, a controller and an output unit. The memory array has storage cells arranged as data rows and complement rows. The multiple row decoder activates more than one row of the memory array at a time and the controller indicates to the multiple row decoder to activate data rows or complement rows as a function of an input pattern to be matched. The output unit indicates which columns generated a signal, the columns matching the pattern.
