Abstract
This invention needs no priority encoder to connect the plural number of associative memories. The primary searching associative memoryof the associative memoryproduces the intermediate dataobtained after the logical sum operation for the coincident storage data in the confirmed valid state, taking the research dataand the mask information into account, into the intermediate data determination sectionand the internal secondary searching associative memory. The intermediate data arithmetic sectionproduces the valid state to the valid search signalcorresponding to the storage data with the least number of bits in invalid state among the intermediate datasupplied from the first through p-th associative memory. The first through p-th secondary searching associative memorycarries out the search operation for the storage data with the corresponding intermediate dataas the search data, supplying the match line. When the corresponding valid search signalis put in the invalid state, the first through p-th logical sum operation meansputs the all values of corresponding match linein the invalid state, produces data into the address signal producing section, and encodes data to the address output signal
