One embodiment of the present invention is a nanoscale shift register that
can be used, in certain nanoscale and mixed-scale logic circuits, to
distribute an input signal to individual nanowires of the logic circuit.
In a described embodiment, the nanoscale shift register includes two
series of nanoscale latches, each series controlled by common
latch-control signals. Internal latches of each series of latches are
alternatively interconnected with a previous latch of the other series
and a next latch of the other series by two series of gates, each
controlled by a gate signal line.
