World's Densest Memory Cells Created

CowboyNeal posted more than 7 years ago | from the do-what-now dept.

Data Storage 46

toybuilder writes "A Reuters new article reports the development of the world's densest memory circuit at Caltech & UCLA. The circuit has a bit storage density of 100Gb/cm^2; about 100 times the density of today's memory circuits. Interestingly, this new design places memory cells at junctions of a tic-tac-toe-like grid of wires, somewhat reminescent of core memory of the past."

Yet still not dense enough (4, Funny)

Anonymous Coward | more than 7 years ago | (#17764418)

To contain all of Slashdot's dupes [slashdot.org].

Re:Yet still not dense enough (1)

creativeHavoc (1052138) | more than 7 years ago | (#17765706)

The funny thing is, today after getting home I was looking for the old one and couldn't find it. Some one made it easy on me. I almost had to use the search function.

Slashdot editors: write-only memory (0)

And it's pretty damn dense, too.

Maybe this is an improvement over yesterday's record.

Jeez.. (0, Redundant)

FunWithKnives (775464) | more than 7 years ago | (#17764452)

Not only is this a dupe, it's one from yesterday [slashdot.org]. Ugh.

Archangel Michael (180766) | more than 7 years ago | (#17764752)

As opposed to the other kind of dupe, which is what??? From Tomorrow?

Re:Jeez.. (1)

networkBoy (774728) | more than 7 years ago | (#17764888)

My favorite is when the dupe and the first article are both on the main page. Forget what that one was for...

I'm confused. (2, Funny)

FlyByPC (841016) | more than 7 years ago | (#17764464)

Dense is good?

People have been calling me dense for years. But hey, they also called me a geek, so maybe they're right.

only 2 days??? (0, Redundant)

ganjadude (952775) | more than 7 years ago | (#17764466)

and its back???http://hardware.slashdot.org/article.pl?sid =07/01/24/2320248&threshold=-1

do the editors not even read their own site any more???

Re:only 2 days??? (1)

FlyByPC (841016) | more than 7 years ago | (#17764488)

>and it's back??

Must be /. editors have started using some of that new "dense" memory already!

Silicon Valley Companies Reach Singularity; Vanish (1, Informative)

Anonymous Coward | more than 7 years ago | (#17764490)

Maybe Ray Kurzweil and Vernor Vinge were on the money. Except, it occurs to me, if the silicon valley companies come up with a singularity, why do they have to bring the rest of humanity along? In fact, the faster they accelerate, the longer it will take to disseminate the advanced technology, until at some point it cannot disseminate fast enough. So they'll just disappear by themselves!

Incidentally, I'm not sure this is a dupe; the first article said that HP did it and this one says that now CalTech has done it. They were working independently. It's nice to have an independent lab reproduce your results. Just ask Pons and Fleischmann.

Its the same... (2, Informative)

Fallen Kell (165468) | more than 7 years ago | (#17764618)

All you need to know is that they both talk about the same exact 160,000 bits memory implementation to know it is the same. No two competing groups would both come up with that same strange way of expressing the memory size. Anyplace else would say 20,000 bytes, or 19.53125 KB, not 160,000 bits.

Re:Its the same... (1, Informative)

Anonymous Coward | more than 7 years ago | (#17764716)

The article says they were working in cooperation.

Re:Its the same... (2, Insightful)

evanbd (210358) | more than 7 years ago | (#17765056)

Actually no... most memory chips are sold in bits, kbits, mbits, etc. SRAM, DRAM, Flash, anything -- individual memory chips are mostly sold in bits. This (oddly, perhaps) includes both chips that are intended to be aggregated into RAM sticks and 16 bit wide SRAM chips intended for embedded devices. I have no idea why, but I've gone shopping for discrete memory chips before and that's largely the way it is.

Now, obviously two groups coming up with the same size and density in two days suggests a slashdot dupe, but two expressing it in bits? No, that's not at all surprising.

Re:Its the same... (0)

Anonymous Coward | more than 7 years ago | (#17765298)

Many reasons to use bits... the first is technical: the bit is the least ambiguous measure of storage. A byte is generally considered to be 8 bits, but can vary with parity bits and various other architecture anomalies. The primary reason, though, is likely to be plain old marketing: expressing in bits makes it 8 times as big as expressing in bytes. Kinda like convincing a young child that they have more cake by cutting their piece in half, or convincing investors that they have a larger share by splitting stocks (Okay, that is probably more for simple management and allowing people to get in on ownership with a smaller investment. But... hey.)

World's densest memory cells (2, Funny)

sokoban (142301) | more than 7 years ago | (#17764664)

Apparently Slashdot editors have been found to have the world's densest memory cells. You can't even get them to remember what happened yesterday. That's what I call dense.

They may dup sometimes... (5, Funny)

esrobinson (1028500) | more than 7 years ago | (#17765030)

They spent all that time and effort on it and they were beaten by a day.

By people from the same institutes too!

Already something "better" (1)

ILuvRamen (1026668) | more than 7 years ago | (#17765140)

wow they made a circuit with 100GB/cm2 that we'll never see in a real memory device for like ever. Good thing I can hop on over to inPhase and store 300 GB on a 130mm by 3.5 mm disc (that's 350 GB/in2 density which I think is like 25 GB/cm2) and have it up and running at my business in like a week for like $4000. Not exactly a wise idea to try to invent something that might just barely beat something that's commercially available right now because by the time it's ready for commercial applications, holographics will blow it away. The discs have a shelf life of 50 years or 10 million read cycles in use and the read write speeds are insane. Sorry to have kinda killed the wow factor but it's not that wow after all :-P Btw what ever happened to the "nano punch stamps" that could hold like 10 terabytes on a 1 inch square area by impacting the 0's and 1's a couple nanometers apart that was reported on slashdot a long time ago?

World's Densest Slashdot Editors Created (1)

KNicolson (147698) | more than 7 years ago | (#17765246)

A Reuters new article reports the development of the world's densest Slashdot editors at Caltech & UCLA. The editors have a dupe storage density of 100Gb/cm^2; about 100 times the density of today's Slashdot editors. Information on how many dupes of the Library of Congress could fit into a 747-full of tubes is still awaited.

Jesus Christ (3, Informative)

OverlordQ (264228) | more than 7 years ago | (#17765648)

Jumping Jesus on a Pogo Stick people, a good sweeping majority of the comments so far have been "OMG DUPE", "OMG SLASHDOT SUXORS", "EDITORS ARE STEWPID".

How about next time there's a dupe, you just don't comment. Let the people who have something intelligent and informative to say post. Also, not everybody might have seen it the first time.

Lighten Up.

Re:Jesus Christ (1)

Mad Dog Manley (93208) | more than 7 years ago | (#17768784)

Also, not everybody might have seen it the first time.

Tough. This isn't Digg, where articles are posted to the front page multiple times (sometimes as much as a dozen times over a two week period). Slashdot hosts far less articles, but they are of generally much higher quality (than Digg).

Dupe? Then do something about it. (3, Funny)

doomy (7461) | more than 7 years ago | (#17765798)

If it's a dupe, just click on the FireHose Link [slashdot.org], then find the article (some magic involved). After that vote against it.

I believe this works.

You know... (1)

Nom du Keyboard (633989) | more than 7 years ago | (#17774434)

You know, there's still lots of empty space in my PC case. Memory chips that are "too big" have yet to be pushing themselves out the air vents.
