Abstract
A clock delay circuit of the type used in semiconductor dynamic read/write memory device employs pull-up and pull-down output transistors connected in series between a voltage supply and ground. Excess current in this series path is minimized by a circuit holding the gate of the output pull-up transistor to a low voltage until the gate of the pull-down transistor goes low. Then, the gate of the pull-up transistor is booted above the supply voltage. Also, tendency for the output voltage to rise above ground during the delay period is avoided.
