New transistor breaks speed record

A few million of them at .1 microns would make a gnarly processor.

I know you don't have a lot of tech on your science ping list, but this one has physics too, and looks like a big step. Could be worthy.

[randog]

And a bi-polar, to boot. What's old is new again.

[InterceptPoint]

The new device is a so-called bipolar transistor, which is very different from the more well-known field-effect transistor.\

OK, it's a small thing but when I think transistor I'm thinking of a bipolar transistor. When I think FET then I'm thinking about a field effect transistor.

Of course I'm old enought to remember germanium transistors and the silicon versus germanium debate so maybe things have changes and I didn't notice.

600 GHz is very nice. Now I want a dual Pentium, quad core, 128 bit 600 GHz PC with a 100 GHz FSB. Something that will bring up the photos of the grandkids a little faster.

[DrewsDad]

Now wait just a pico-second(or 1.66).

[JamminJAY]

Maybe want to wait for This

OK ... quick what's a SNn7400

Extra credit ... whats a 555

[clamper1797]

Thats SN7400 ... damn keyboard

[Spktyr]

Except it will never be produced in the US because someone somewhere will claim that this product causes hair loss and sue, bankrupting the manufacturer. :-P

Interesting, but it's not quite for my list. Try neverdem, who has a "health and science" list. I don't know if there's a computer ping list. Maybe ShadowAce, who has the "Firefox browser" list, and rdb3 has a Linux list. If in doubt, farmfriend keeps the list of ping lists.

The SN7400 is a quad dual input positive NAND gate, the 555 is a timer IC.

Any more, professor?

[Little Pig]

Is it just me, or does the way this works sound an awful lot like a synapse?

[Willie Green]

It sounds promising, but it ain't official until they test it on the Bonneville Salt Flats.

[RinaseaofDs]

A 555 is a timer.

[clamper1797]

Sure ... What color is the cover of the old TI TTL book.

Extra credit ... what is the color is the cover of the old Signetics TTL book

[Sundog]

555 An 8 pin timer chip // 2 timers per chip.

The new device is a so-called bipolar transistor, which is very different from the more well-known field-effect transistor. In it, electrons are injected from the "emitter" terminal, travel towards the "base" and are then received by the "collector", an arrangement that allows the device to work faster than a field-effect transistor.

I was building these at Signetics in 1984.

[Liberal Classic]

Developed by Walid Hafez and Milton Feng at the University of Illinois at Urbana-Champaign... The new device is a so-called bipolar transistor...

Are you there, HAL?

[clamper1797]

BTW ... I still have mine

[GeekDejure]

one that can operate at a frequency of over 600 gigahertz.

Big deal . . . my cheeks vibrate at 601 gigahertz each and every time I traf !!! ;-))
