ABSTRACT:
An associative memory4for primary searching operation of an associative memory23supplies a valid state to a primary match line13corresponding to storage data coincident with search data10taking mask information into account, and supplies a value obtained from a result of a logical sum operation (an OR operation), with a valid state for the storage data as true, of all said coincident storage data to a counting means25as intermediate data15. The counting means25supplies a result of an operation to the intermediate data15for counting the number of bits in an invalid state for the storage data to an associative memory3for secondary searching operations as secondary search data19. Among secondary storage data obtained by carrying out said operation to said storage data, the associative memory3for secondary searching operation supplies a result of carrying out the searching operation of the secondary search data19to a secondary match line21. The invalidation means22changes a secondary match line21corresponding to a primary match line13in an invalid state into an invalid state to supply to an external source as a match line11.
