Abstract
A semiconductor logic circuit apparatus which include a first switching element consisting of a field effect transistor for changing holding data, an inverter circuit whose input is connected with one end of the first switching element, a feedback circuit whose input and output are connected with the output and input of the inverter circuit, and a second switching element connected between the output of the feedback circuit and first or second potential. The second switching element is effective for enabling and disabling the feedback circuit. The first and second switching elements are opened/closed in reverse phase to each other. Feedback of the feedback circuit is prevented until the inverter circuit is driven from its "0" to its "1" holding state, so that driving of the inverter circuit becomes easy and operational stability and operating speed are enhanced.
