[Wired] Japanese Company Builds Optical RAM - 40 gigabits/s

post #1 of 11

Researchers at Japanese telecom giant NTT have built an optical random access memory (o-RAM) chip — a conceptual cousin to the electronic memory in your computer. The goal is not to make a light-speed replacement for DRAM. That’s out of the realm of possibilities for the foreseeable future. Rather, the idea is to make fast, efficient storage buffers for internet routers and the communications switches that connect thousands of servers in data centers.

The NTT researchers built a 4-bit prototype that operates at 40 gigabits per second. If the technology were scaled up, a 1 megabit device would take up a square centimeter and consume less than 100 milliwatts. “Our RAM is just a 4-bit memory. We need to increase the scale of integration,” says NTT researcher Masaya Notomi.
Quote:
Optical RAM doesn’t have to hold very much to be useful for networking. Buffers on future optical routers could be very small compared to the electronic memory used today, says Nick McKeown, an electrical engineering and computer science professor at Stanford. McKeown calls a device that can hold 500 kilobits and read and write data at 100 gigabits per second “very interesting.”

Each cell in NTT’s o-RAM is a nanoscale photonic crystal — a type of material that channels light in very small spaces. Varying the intensity of the light entering the chip switches the material between transparent and opaque, two states that can represent 1s and 0s in digital signals.
Quote:
Another driving force is the future of Internet servers and supercomputers: many-core chips. These chips require fast communications between processor cores, leading to a network-on-a-chip architecture. “Optical RAM will be implemented inside ultrafast many-core CPU chips with a photonic network design,” says NTT’s Notomi. “This strategy will [ultimately] need to introduce optical routing in a chip, and then optical RAM will be called for.”

Wooooooooooooooooooooooooooooooooooooooooo!

WhoooooooooooHooooooooooooooooo!

I called this a few years back, that one day we will have Crystals and Gems and lights beaming back and forth inside the Desktop haha



So what system you running?

My thougth was there will be new avenues for performance gains, Light Shielding, who knows

instead of Watercooling and LN2, the new big thing, will be running the machine in a Perfect Vacuum lol

Installing additional crystals to capture certain portions of the Prism its all fake so make up whatever you think soudns cool, and maybe it will exist in the future =)

the true overclockers and hackers of this distant world will use str8 up rocks

I just Image Chunks of Crystals and Rocks sticking out of a PCB


Or maybe there is no PCB? Maybe its all str8 up crystal!

heres my PC

700



And this one is Bill Gates' Computer

This is pretty cool, but when I read it the only thing that popped in my mind was running servers off of light power and a voice in the background yelling "WE REQUIRE ADDITIONAL PYLONS!"

OH then they will compress all these parts into a size of a pen with an optical output which beams out holograms. At the same time surround you with a 360 of your current desktop which you can access anywhere and only needs to be recharged once a week. That would be awesome.
