An information retrieval system includes two content addressable memories to be searched for m-bit/n-bit codes identical with m-bit/n-bit retrieval key sub-codes, a data memory storing pieces of information relating to different retrieval keys expressed by the combinations of the m-bit/n-bit codes in addressable memory locations assigned addresses, respectively, and an address generating unit supplied with addresses of the m-bit/n-bit codes identical with the m-bit/n-bit retrieval key sub-codes from the content addressable memories so as to generate a target address from the addresses for accessing the piece of information relating to a given retrieval key, whereby the two content addressable memories are searched for the m-bit/n-bit codes substantially in parallel.
