Array-Based Memory May Put a Terabyte On a Chip

Lucas123 writes "A new type of flash memory, called array-based memory, could offer a terabyte of data on a single chip within the next decade by bypassing current NAND memory technology, which is limited by the miniaturization capability of lithography. According to the Computerworld story, start-up Nanochip Inc. is being backed by Intel and others, and over 11 years has made research breakthroughs that will enable it to deliver working prototypes to potential manufacturing partners next year. And by 2010, the first chips are expected to reach 100GB capacity."

USB 3.0 desperately needed here...

[Zymergy]

USB 3.0 or *something faster* will be required for devices this large in portable storage capacity.. USB 2.0 is ~480Mbps (theoretical max) and it would take forever to transfer a terabyte over USB 2.0.

I'm thinking eSATA may fill the gap, though it does have the drawback of not powering the device directly. Of course, there is an easy solution to that: have a device which runs on 5VDC at less than 5mw. Connect the data port to eSATA and the power port to the USB port, and you're done.

cantilever memory is decades old

[davidwr]

Memory device with dual cantilever means [freepatentsonline.com], United States Patent 5036490, IBM, published 07/30/1991. TFA talks about IBM's Millipede project, which looks like something similar.

A better summary would have said "Improvements to cantilever memory hold promise for 1TB chips by 2018" or something similar.

Wikipedia has some information [wikipedia.org] on non-memory uses of micro-cantilevers.

Not to be picky, but NAS is "Network Attached Storage" You have an external hard drive.

10GigE [wikipedia.org] is faster than USB3, and on the market right now.

Problem solved.

For some, it's both -- a USB enclosure plugged into a router.

Sounds similar to a DLP TV, to me. On those things, the mirrors are flexing up to 60 times each second, the whole time the TV is on. I remember reading something about the wear issue, and they found that if they constrain the flexing (less than 17 degrees, IIRC) that wear was not an issue. Apparently wear rises rapidly with the degree of the flex.

I don't know how you can write, but not read. It turns any USB storage device into NAS.

It is already free/open source, under the Lucent Public License (assuming you can bring yourself to run non-GPL code, I know it's hard for some people here). Plan 9 Port [swtch.com] will allow you to run Venti on Linux, but ideally you just download Plan 9 [bell-labs.com] and install it on your file server; you can then use v9fs [swik.net] to access Plan 9's fileservers.
I do my work natively under Plan 9, so I don't have much experience using Venti and Linux.

I think you mean less than 500mw(the limit a single USB port can supply), not 5mw. Most 2.5" laptop harddrives meet this requirement, not sure about other types.

Re:USB 3.0 desperately needed here...

[ThisNukes4u]

As yes, you got me. USB ports supply up to 500 mA(not mW). The total power a single USB port can supply is 2.5W
