E, Hoff for the realization of automatically adapted ADALINE neurons </li></ul><ul><li>The first working memistors were made of ordinary pencil leads immersed in test tubes containing copper sulphate- sulphuric acid plating baths.

  23. 28. The three methods
  24. 29. NIST ’s effort to built the first nonvolatile fast flexible memory for defense purpose led them to the invention of first ever flexible memristor in July of 2009 This memristor uses the same material as that of HP’s memristor but in a much simpler way

  34. 43. To conclude <ul><li>It is sure that Memristor is going to revolutionaries the 21 st century as radically as the transistor in the 20 th century </li></ul><ul><li>But Memristor will have to wait a few years for a killer app like transistor which had to wait almost a decade after it’s invention for the killer app in the form of hearing aids </li></ul><ul><li>Finally as Leon O Chua mentioned </li></ul><ul><li>It’s time to rewrite all the EE textbooks ” </li></ul>
