Memristor computers that work like human brains

The team at HP Labs responsible for building the world=92s first
memristor in 2008 have discovered their creation has more capabilities
than was previously thought. In addition to retaining a history of the
information it has acquired making it useful for memory storage
devices, the team has found it can perform logic that could change the
way computer systems are designed and enable faster more efficient
computers.

The memristor (short for memory resistor) represents the fourth basic
circuit element in electrical engineering, joining resistors,
capacitors, and inductors. The discovery that it can perform logic
opens up the possibility of computation one day being performed in
chips where data is stored, rather than on a specialized central
processing unit (CPU).

Memristors offer many advantages. They require less energy to operate,
are faster, and can store at least twice as much data in the same area
as present solid-state storage technologies such as Flash memory. They
are also virtually immune from radiation, which can disrupt
transistor-based technologies =96 making them an attractive way to
enable ever smaller but ever more powerful devices. And because they
do not =93forget,=94 memristors can enable computers that never need to be
booted up and can be turned on and off like a light switch.

HP Labs has already created development-ready architectures for memory
chips using memristors and believes it is possible that devices
incorporating the element could come to market within the next few
years.

HP researchers also have designed a new architecture within which
multiple layers of memristor memory can be stacked on top of each
other in a single chip. In five years, such chips could be used to
create handheld devices that offer ten times greater embedded memory
than exists today or to power supercomputers that allow work like
movie rendering and genomic research to be done dramatically faster
than Moore=92s Law suggests is possible.

The team also says the discovery means that eventually memristor-based
products might replace the silicon in the smart display screens found
in e-readers and could one day even become the successors to silicon
on a larger scale.
