Abstract
An amplifier circuit for sensing and refreshing stored information, utilized with a voltage supply. The amplifier is of the type that is capable of assuming first and second conditions in response to signals at first and second input nodes. The circuit comprises first and second cross coupled devices each capable of assuming a high and low conduction state. Restore circuitry means is provided connected between the active devices and the voltage supply for selectively connecting the supply solely to the device assuming a low conduction state. In a dynamic random access memory embodiment means is further provided for alternately precharging the nodes to a predetermined state and applying stored information to the nodes to cause the amplifier to assume first and second conditions in response to stored information.
