New Scientisthas a feature article on five conceptual heir to scoot memory board . These are all technology presently under development that could fit terabytes of info on a single petite chip — and some of them are n’t too far off .
The five here considered are MRAM ( using two slight layers of charismatic cloth ) , FeRAM ( which creates polarization through ferroelectrics ) , PCRAM ( using laser , sort of like with CDs and DVDs ) , RRAM ( a variation on PCRAM that use electrochemical reactions instead of heat - induced changes ) , and Racetrack ( which , honestly , I realize even less than the other four , severely as that is to believe ) . If you ’re not a sciencey case , descriptions of these technology may fathom like adults in Charlie Brown ’s world , but they could be the next gyration in data storage — so read up .
