IBM develops ‘instantaneous’ memory, 100x faster than flash

29 Jun
You've got to hand it to IBM's engineers. They drag themselves into work after their company's 100th birthday party, pop a few Alka-Seltzers and then promptly announce yet another seismic invention. This time it's a new kind of phase change memory (PCM) that reads and writes 100 times faster than flash, stays reliable for millions of write-cycles (as opposed to just thousands with flash), and is cheap enough to be used in anything from enterprise-level servers all the way down to mobile phones. PCM is based on a special alloy that can be nudged into different physical states, or phases, by controlled bursts of electricity. In the past, the technology suffered from the tendency of one of the states to relax and increase its electrical resistance over time, leading to read errors. Another limitation was that each alloy cell could only store a single bit of data. But IBM employees burn through problems like these on their cigarette breaks: not only is their latest variant more reliable, it can also store four data bits per cell, which means we can expect a data storage "paradigm shift" within the next five years. Combine this with Intel's promised 50Gbps interconnect, which has a similar ETA, and data will start flowing faster than booze from an open bar on the boss's tab. There's more detailed science in the PR after the break, if you have a clear head.

Detroit DIYer cooks up stronger, lighter steel, shames scientists

Flash Bainite
You'd be forgiven for dismissing an amateur metallurgist if he claimed to have improved upon the presumably perfected technology of steel making. But Flash Bainite, the creation of Detroit entrepreneur Gary Cola, wowed a team of Ohio State University engineers by turning centuries of alloy processing on its head. Instead of heating the metal for hours or days, this well-equipped DIYer boosted the temperature -- quickly baking, then cooling sheets of steel that are 7-percent stronger than other forms and tougher than some titanium alloys. Flash Bainite is also more ductile than other steels, allowing it to crumple more before breaking -- perfect for absorbing impacts. Obviously this means stronger and lighter cars, laptops, and armored vehicles but, since the process takes all of about 10 seconds, it's also more energy efficient and cheaper than traditional steel making. Now, who has the number for the Nobel Prize committee?
