Macronix plans to heat up flash memory to keep it from burning out
Despite the looming threat of being replaced by phase-change memory, contemporary memory modules aren’t quite ready to be shown the door — engineers at Macronix have found a way to revive spent NAND flash cells. Most flash modules fail after being written to and erased about 10,000 times, but Macronix found that the tired memory could be restored by baking it for extended periods of time. The team funneled the time consuming and cumbersome solution into a more practical package: a redesigned memory chip that packs onboard heaters. The new modules are designed to periodically heat focused groups of memory cells to 800 °C (1,472 °F) for a few milliseconds, effectively “healing” worn cells.
Researchers found that heated chips could tolerate more than 100 million write/erase cycles and erased faster at higher temperatures. The team said the power drain of the heaters shouldn’t effect battery life, either — chips don’t have to be heated often, and when they do, it can be done while prospective devices are recharging. Macronix will be presenting the technology at the IEEE International Electron Devices Meeting next week, but project deputy director Hans-Ting Lue wouldn’t say when the company plans on taking the technology to market. Lue was willing to speculate on what might become of it, however. “This may evolve into a ‘thermally assisted’ mode of operation that gives both better performance — such as the faster erasing — and better endurance flash memory.” Faster, more reliable, super-heated memory. Sounds fine by us.

Ford, GE and University of Michigan team on sensor to track EV battery life, keep us on the road
Believe it or not, EV battery life is still something of a Pandora’s Box, even for automakers: they can tell you the battery pack’s current and voltage, but not how it’s really performing under pressure. Ford, GE and the University of Michigan are uniting to unlock that mystery through a new ARPA-E project. In its role, GE is developing a minuscule sensor array that will track the nuances of battery cells that existing technology misses; it will promptly hand the baton to researchers at the University of Michigan, who plan to both prove that GE’s data is on the mark as well as develop tricks for predicting behavior. Ford handles the last mile, almost literally: it’s planning to fit the GE sensor technology to one of its cars and test in a more realistic environment. Before you fantasize about knowing the lifespan of your Focus Electric’s battery down to the minute, however, the new alliance is stressing that it’s only just getting started — there’s another three years and $3.1 million to go before the project wraps up. If all goes according to plan, though, we’ll have electric cars and plug-in hybrids that can not only tell when they’ve seen better days but can eke out extra miles through smarter battery designs.

Keep your bands straight with Adafruit’s Ohm Sweet Ohm cross-stitch kit (video)
Doesn’t it just seem like yesterday when Grandma used to embroider your resistor charts for you? But now that you’re grown up, Adafruit wants you to cross-stitch the Ohm Sweet Ohm color band guide yourself with their handy kit (dog not included). Spec-wise, it’s loaded up with 16 skeins of floss, two size 24 tapestry needles, 15 x 18-inch 14-count aida cloth and a 6-inch “super grip lip” embroidery hoop, all for $29.95. You’ll also get a full color printed pattern with instructions on making the project, then how to mount it on the wall or sew it onto Spot’s favorite pillow. So if you can never remember whether yellow in the C-band is four significant figures or five, and want an Ohm-y reminder — then check the video after the break for more info.

BlackBerry Curve 9310 / 9320 turns up at FCC, fails to keep a low profile
FCC docs can, from time to time, turn up some welcome device surprises. Not so in this recent RIM filing, as we’re treated to yet another in a long line of leaks for the company’s Curve 9310 / 9320. The BB OS 7.1 handset, bearing the FCC IDs L6AREY20CW and L6ARFD30CW, has already made several appearances around the globe, preparing for a low-end market berth in Australia, India, Vietnam and the UK. So, aside from RF testing data indicating WiFi b/g/n and Bluetooth radios, our familiarity with the phone’s specs come from its prior in-the-wild jaunts. Should a single-core processor, 512MB RAM, 3.2-megapixel camera and hardware QWERTY tickle your mobile fancy, then by all means click on the source below to fill your cup of this U.S. pre-release federal formality.

Netflix backtracks on Qwikster, will keep DVDs and streaming under the same URL
The Netflix Contrition Tour 2011 continues today, as the company announced today that it won’t be spinning off DVD-by-mail rentals into a new company called Qwikster. While the plan for DVD operations to be separated internally appears to still be under way (no word yet on the promised videogame rental option), for customers things will stay the same, with one login and one website. While the retreat will probably prompt even more speculation about the company’s true plans, CEO Reed Hastings has issued yet another apology to customers, admitting Netflix may have moved too fast this time.
Another sticky issue that’s not so easily dealt with is the recent pricing change that took effect last month. While many speculated at the time about what percentage of customers would see higher prices as a result, spokesperson Steve Swasey reveals it affected about half of the company’s subscribers. For the rest who had signed up for the $7.99-streaming only package (an option selected by the overwhelming majority in the quarter before the change) prices didn’t go up at all. We have our own ideas about what the pricing should be, but it seems Netflix has finally realized not all customers got the message that it’s a streaming company now, and tacking DVDs onto its new primary offering for only $2 extra just didn’t work. Since all that uproar Netflix has announced a few new / expanded content deals for its streaming service, with Discovery and exclusive rights to previous seasons of The Walking Dead from AMC. But with renewed competition from the likes of Blockbuster and Amazon only time will tell if it can do enough to stop the subscriber bleeding. The Netflix Q3 earnings report is due October 24th — think that will be an interesting call to listen in on?

Leave a commentHelp for the lost: a fabric antenna to keep you from being a castaway
Doesn’t look like much, does it? But the next time you’re lost at sea, you just might be thankful you’ve got it. That little square of fabric is actually a flexible antenna designed for the Cospas-Sarsat distress signal network, a Cold War-era system built to help pinpoint missing ships, planes and people. Designed to be sewn into a life vest, the antenna broadcasts an emergency beacon at a low frequency for greater range; in field tests, that helped rescuers find it within minutes. It’s also tear- and water-resistant, which you’ll be grateful for when you’re being tossed around like a ragdoll in a sea of whitecaps. The technology was developed by the European Space Agency in partnership with a Finnish company. Next on their agenda? A round, floating companion for the marooned, codenamed Wilson.

Leave a commentMicrosoft Research-backed e-reader prototype can’t keep its text to itself (video)
We’ve seen plenty of dual-screen devices over the past couple of years, and they never fail to make us a little sentimental for Microsoft’s stillborn Courier concept. That goes double for this reader device, which made an appearance at this week’s CHI conference in Vancouver, seeing as how Microsoft Research apparently played a role in its development. But this gadget, presented by the University of Maryland’s Nicholas Chen, is clearly its own beast — and it’s an awesome looking one at that. The reader actually only has one screen, but it can connect wirelessly with other units, letting the users do things like send links between devices. It will also clip magnetically to another unit, so you can look at two pages of the same document at the same time, just like one of those oldfangled book-type things. Fans of awkward intros, check out the video after the break.
[Thanks, Winston]
