Abstract
In a memory device, a shift-register comprises a plurality of stages for transferring sequentially a pair of signals which have mutually opposite phases. Each stage has a comparator circuit which compares the pair of signals and generates a pair of fixed voltage signals. By this construction, high-speed operation of the memory device, low power consumptions, and high-capacity load driving are achieved.
