ABSTRACT:
An arithmetic logic register stack device is provided on a single semiconductor chip, which device comprises a building block for digital systems. The device of this invention is expandable, which enables performing operations with binary numbers greater than that with which a single device is capable of performing. Unique circuit design is provided for multiple use of connector pins to the semiconductor device, thereby allowing for an increase in the complexity of the circuits that can be integrated onto a single semiconductor chip or placed into a package with a given number of pins.
