Something similar is true of the logic circuits in computers' microprocessors. These could be made faster, and would consume less energy, if they were able to store information themselves instead of fetching it from separate memory chips or hard drives. The problem is that the transistors used to make logic circuits hold their electronic state, and therefore any data they contain, only when powered up. The choice engineers face is thus between supplying continuous power to a transistor, so that it can retain its memory (which costs energy), and ferrying data that would otherwise be lost to and from so-called non-volatile memory devices that do not require continuous power (which costs time). Cracking this problem--so that transistors can act as their own non-volatile memory--would make all computers faster. It would be particularly valuable, though, for mobile devices. These could be made smaller and lighter, since they would require fewer components. And they could go for longer between charges. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
