IBM develops 'instantaneous' memory, 100x faster than flash

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.
Always remember.........Just because you have never seen something, does not mean that something does not exist.
