Looking now at a particular subarray inhibit circuit, for example that comprising load transistors 621 and 631 and switching transistors 661, 671, and 681, it will be seen that when transistor 68] is nonconductive, V potential (less the drop through load transistor 631) is applied over the line 691 as an lNH-IN, signal, The IN- H-IN, signal is an inhibit signal and is applied to the state register
