Abstract

See full text

In a semiconductor circuit a floating node is set to any voltage by utilizing a control signal applied to a refresh terminal and has a period shorter than that of a clock signal. The circuit includes first and second transistors connected between a first clock terminal and first power supply terminal, third and fourth transistors connected between the refresh terminal and the first power supply terminal, and fifth and sixth transistors connected between a second power supply terminal and the first power supply. Gates of the fourth and fifth transistors are connected to an input terminal, a gate of the third transistor is connected to a second clock terminal, a gate of the first transistor is connected to a node between the fifth and sixth transistors, gates of the second and sixth transistors are connected, and a node between the first and second transistors is connected to an output terminal.
