Multistate memory circuit

Claim 1

AN INFORMATION STORAGE CIRCUIT EMPLOYING AN M OUT OF N CODE, WHEREIN N IS AN INTEGER EQUAL TO OR GREATER THAN FOUR AND M IS EQUAL TO N/2 WHEN N IS AN EVEN INTEGER AND N/2+1/2 WHEN N IS AN ODD INTEGER, COMPRISING AN INPUT CIRCUIT FOR SUPPLYING N!-M!(N-M)! CIRCUIT INPUT SIGNALS, AN OUTPUT CIRCUIT FOR PROVIDING N OUTPUT SIGNALS, THE COMBINED MANIFESTATION OF THE OUTPUT SIGNALS AT SAID OUTPUT CIRCUIT BEING INDICATIVE OF THE STATE OF INFORMATION STORED IN THE CIRCUIT, A FIRST GROUPED OF COMBINATORIAL LOGICAL GATES EQUAL TO N, EACH OF THE GATES PROVIDING ONE OF THE OUTPUT SIGNALS AT SAID OUTPUT CIRCUIT IN RESPONSE TO N!/M!(N-M)! INPUT SIGNALS SUPPLIED TO EACH OF THE FIRST GROUP OF GATES, (N-1)!/(M-1)!(N-M)! OF THE SIGNALS APPLIED TO EACH OF THE FIRST GROUP OF GATES BEING SUPPLIED FROM THE INPUT CIRCUIT ACCORDING TO THE M OUT OF N CODE UTILIZED IN THE CIRCUIT A SECOND GROUP OF COMBINATORIAL LOGICAL GATES EQUAL IN NUMBER TO N!/M!(N-M)! EACH OF THE SECOND GROUP OF LOGICAL GATES BEING RESPONSIVE TO A DIFFERENT M OF THE N OUTPUT SIGNALS TO PROVIDE A FEEDBACK SIGNAL, AND MEANS COUPLING EACH OF THE SECOND GROUP OF LOGICAL GATES TO AN N-M NUMBER OF THE FIRST GROUP OF GATES, SO THAT (N-1)!/M!(N-M-1)! OF THE INPUT SIGNALS SUPPLIED TO EACH OF THE FIRST GROUP OF GATES ARE SUPPLIED AS FEEDBACK INPUT SIGNALS FROM THE SECOND GROUP OF LOGICAL GATES.
