Cutting Edge Homework Development
Goordon H. Moore
• Co-founder of Intel
• Observed the number of transistors in
chips would double every 18-24 months
• So far, Moore’s Law has fairly accurately
predicted the growth of transistor counts.
Today’s Chips
• Manufacturers try to make transistors as
close together as possible to make a chip
smaller and faster.
• Create so much heat only part of the chip
can be used at a time
• Chips are using wires that are as thin as
90 nanometers
The theory
• Wires can only get so thin. Before the
distances between conductors is not
sufficient to differentiate between 0 and 1
(off or on) and current is prone to leak to
the insulating material, causing unintended
shorts
• The thinnest a wire can get is estimated at
100 nanometers
Intel’s Solution
• Use more cores in processors
• Replace SiO2 with a new dielectric (a
nonconductor of direct electric current)
known as “high-K”. However it is not
compatible with their current gate
electrode.
Alternatives: Spintronics
• Spintronics is an emergent technology
which exploits the quantum propensity of
electrons to spin as well as making use of
their charge state. The spin itself is
manifested as a detectable weak magnetic
energy state characterised as "spin up"
and "spin down"
Alternatives: Nanotubes
• Nanotubes are a one atom thick layer of
graphite that has been rolled into a
cylinder. Nanotube based transistors can
be made to operate at room temperature
and unlike silicon, they don't leak.
Alternatives: Crossbar Latches
• This technology is being created by
Hewlett-Packard, and allows much the
same functionality of transistors, except on
a molecular scale. They consist of a signal
line crossed by two control lines.
Depending on the voltages sent down the
various lines, it can simulate the action of
the three major logic gates: And, Or, and
Not.
