Scientists report that they have figured out the chemistry of what actually happens inside a memristor while it is being deployed. Up to now it had been mostly a mystery.
Labs research scientists on May 16 reported a new breakthrough in their
continuing development of memristors-next-generation memory that some industry
people see as an eventual replacement for NAND flash and DRAM storage.
memristor, basically a resistor with memory, apparently has more capabilities
than anybody expected. HP Labs has previously reported discovering that a
memristor can perform logic, potentially enabling computation to be performed
in chips where data is stored. This could mean a radical change in the way
future IT is designed and built.
scientists reported in the May 16 edition of the journal
"Nanotechnology" that they have figured out the chemistry of what
actually happens inside a memristor while it is being deployed. Up until now
this had been mostly a mystery.
HP is confident it will eventually commercialize memristors, this discovery is
important because it will enable HP to greatly improve its performance, Senior
Fellow Stan Williams wrote in the article.
were on a path where we would have had something that works reasonably well,
but this improves our confidence and should allow us to improve the devices
such that they are significantly better," Williams wrote.
The Fourth Basic Circuit Element
memristor-short for memory resistor-is viewed by HP engineers as the fourth
basic circuit element in chip engineering, up there with the resistor,
capacitor and inductor.
Flash Memory Summit
in Santa Clara, Calif., in August 2009, Williams
described the memristor this way
: "This is sort of the missing element
of the processor puzzle. It takes its place alongside the resistor, capacitor
and inductor [as the fourth basic circuit element in chip engineering]. And it
could change the way we do IT."
summary, let's just say adding a memristor to a solid-state NAND flash drive
can be like putting it on steroids.
flash media already owns the fastest I/O speeds known to IT science, increasing
that speed tenfold or by a higher magnitude-HP's conservative estimate at this
time-is certainly an intriguing proposition for processor engineers and IT systems
idea behind the memristor was first publicized in 1971 by Prof. Leon Chua at
the University of California, Berkeley. HP researchers first showed the
memristor's existence in practice.
years later, Nature magazine published HP's finding that the memristor exists,
and in 2009, engineers at HP Labs showed that memristors could be stacked,
suggesting that a chip could offer four to eight times the memory capacity of
April 2010, HP officials said its researchers had found that the memristor also
could perform digital logic, setting the stage for the creation of a memristor
product that could act as both a computing chip and a storage technology,
taking the place of traditional storage technologies-including flash and hard
drives-and even CPUs.
