ABSTRACT:
An efficient Content Addressable Memory array for Classless Inter-Domain Routing with each CAM cell including an additional storage unit for storing the prefix length associated with the contents of the cell. An enabling logic connects the prefix length value to a wired OR plane common to all CAM cells, and a sequential bit wise comparison unit has its inputs connected to the wired OR plane and the additional storage unit with its output controlling the enabling logic.
