HTTP:: 039 Phase Change 039 Materials to Replace Flash Memory
--------
One of the most widespread types of memory today is the “flash” one, the kind that can be found in the average USB drive. The popular, non-volatile technology is, however, beginning to reach its limits, as efforts to fit more data into smaller devices are becoming increasingly difficult. That's why Italian experts at the Laboratorio Nazionale MDM, in Milan, are currently looking for new architectures to overcome these hurdles. The answer, they believe, lies within “phase change” or “resistive change” materials, which store data by changing their electrical properties, ICT Results reports. Dr. Grazia Tallarida, the coordinator of the new VERSATILE project for the Laboratorio Nazionale MDM, says of the challenges facing flash drives today that, “Making these devices smaller and also enlarging their capacity is becoming more and more difficult. So there is a lot of work now to find different technologies for non-volatile memories.” Talking about the newly prop!
osed type of memory, the expert adds that, “These are materials in which you store information â€" zero or one â€" by changing the electrical properties. They just need a voltage drop across them to be switched between an ‘off’ state and an ‘on’ state.” ...
