ABSTRACT:
An integrated circuit is provided comprising a first NMOS transistor; a first PMOS transistor; a second NMOS transistor; a second PMOS transistor; a first bias voltage node coupled to a first source/drain of the first NMOS transistor; a second bias voltage node coupled to a first source/drain of the second PMOS; a third bias voltage node coupled to a gate of the first PMOS transistor; a fourth bias voltage node coupled to a gate of the second NMOS transistor; a pull-up node coupling a second source/drain of the first NMOS transistor to a first source/drain of the first PMOS transistor; a pull-down node coupling a second source/drain of the second PMOS transistor to a first source/drain of the second NMOS transistor; an input node; a storage node coupling a second source/drain of the first PMOS transistor to a second source/drain of the second NMOS transistor; an output node; an input switch coupled to controllably communicate an input data value from the input node to a gate of the first NMOS transistor and to a gate of the second PMOS transistor; and an output switch coupled to controllably communicate a stored data value from the storage node to the output node.
