Abstract
The output of a fast-acting ratioless logic circuit is monitored by a sensing device, and when one selected logic output is sensed, a voltage is applied to the output node to latch the output to that state. To effect rapid return to the other state, a switch is provided to deactivate the applied voltage when the output node is established at the other state. The latching is made permanent by the further application of a refresh clock which periodically pulses the output node whenever the one selected state is latched.
