@resistion, I agree with you completely on that point. The use of spintronics, effective as it looks like its going to be, will bring about a conglomeration of new challenges for IT managers if implemented. It will push the disposal of used computers and laptops close to the top of the IT managers' concerns. The fact that the new technology can store data for years without power means that all unused machines must be destroyed or cleaned completely in order to keep any residual data or information away from the reach of hackers.
If this new technology proves to be successful then it could literally revolutionize modern day computing. Am not exactly sure where the difference between SDRAM and DRAM especially when it comes down to the exactly how the memory is stored in terms of charges but going by what has been so elaborately outlined within this article it is clear that there will be a vast improvement in that particular respect if this new spintronics technology proves successful and is adopted.
This article reminds me of articles written by the great Hugo Gernsback, inventor, electronic industry entrepreneur, writer and editor/publisher of over 40 magazines. He is sometimes called "The Father of Science Fiction" along with H.G. Wells and Jules Verne. Hugo was involved with the first television broadcasts and is considered a pioneer of amateur radio. In April 1908 he founded Modern Electrics magazine covering electronics and radio. In each April edition of Radio Electronics he would have a convincing fictitious article about a major electronic breakthrough that would be revolutionary. I remember one of these articles in the late '50s that described various video disk technologies that actual came to fruition decades later. This website features the April 1958 issue of Radio Electronics which outlines Hugo's influence in early electronics: http://swtpc.com/mholley/RadioElectronics/Apr1958/RE_Apr1958.htm
