PURPOSE:To attain high speed retrieval and to eliminate waste of memory, by giving an indexing value to a storage device and outputting an address of the storage device written with the index. CONSTITUTION:When the value of an index in n-bit retrieved in an index register 1 is set, the value of the index register 1 is given to N-set of comparator circuits 3 through an internal bus 11. Further, all of N-set of memories 2 are selected and the storage content is given to the comparator circuits 3 respectively via a bus 12. The comparator circuits 3 compares the storage content in n-bit through the internal buses 11, 12. When only one information of the same content is stored in the N-set of memories 2 each, the comparison circuit 3 outputting a coincidence ''0'' signal is <=1. When the storage content of any one memory 2 is coincident with that of the index register 1, the address of the memory 2 is outputted to a bus 14. |
