Abstract
In one embodiment, an associative memory is built using multiple cascaded associative memory blocks, with stored lookup words spanning a same or different numbers of associative memory blocks. A first lookup operation is performed by a first associative memory to generate first matching indications of associative entries of the first associative memory that match both the first lookup word and the first lookup type. A second lookup operation is performed by an end associative memory to generate end matching indications of associative entries of the end associative memory that match both the end lookup word and the end of word lookup type. A final lookup result indicating a matching multi-block spanning associative memory entry based on the first matching indications and the end matching indications is determined and signaled by the associative memory is built using multiple cascaded associative memory blocks.
