Solid-State Memristors can be combined into
devices called crossbar latches
Crossbar latches are the main feature of
current transistors
Transistors are the main building block of
modern electronics
Memristor development predicts that we can
make a new type of transistor 10 times
smaller than the ones today



Crossbar latches allow greater density hard
drives with much greater speeds
GALACA researches have prototyped memory
using memristors that fit 100 gigabytes on
one square centimeter (not cubic)
This version of memristive memory is 10
times faster than the fastest memory today
(DRAM)


Current flowing through a memristor alters
its electrical resistance
Retains that state after power is turned off
This is a perfect feature for nonvolatile
memory
This coupled with tinier circuits could lead to
instant-on computers.


Memristors can be used to make brain-like
circuits because they “remember” the amount
of current that has flowed through them
Researchers recently developed flexible
memory circuits



Professor Leon Chua (first hypothesized the
memristor) proposed an application as an
“artificial synapse” in a circuit designed for
analog computation
Similar to the idea of mimicking brain
neurons
Medical applications are probably the most
promising future for memristor applications




A recent simple linear circuit with a
memristor was used to model adaptive
behavior of unicellular organisms
The circuit became trained of periodic pulses
so that it could anticipate the next pulse
Similar to the behavior of slime molds that
are subjected to periodic changes in their
environment
This type of learning circuit may find
applications in pattern recognition (A.I.)




Since memristors are such a new development the
all of the potential applications have yet to be
thought of
There are endless possibilities of applications of
memristors
“The most valuable applications of memristors will
most likely come from some young student who
learns about these devices and has an inspiration
for something totally new.”
Experts say that this component will break barriers
that people never thought they would see
