Abstract
An improved active pull-up circuit which can be fabricated with reduced number of elements and operate with a small power consumption. A first switch is provided between a refresh voltage terminal and a true circuit node to be pulled-up. A second switch controlled by a potential of a complementary circuit node is provided for operatively discharging the charge of a control electrode of the first switch. A pull-up clock is applied via a capacitor to the control electrode of the first switch.
