memory stories

 
Storing pictures on your camera may be light years different than it was ten or twenty years ago, but the process of creating the actual storage medium is just about as complicated as it used to be. We've got two videos for you: one showing how memory chips are made in 2011, and another showing how Kodak film was made in 1958.
 
Conventional semiconductor memory encodes data (1s and 0s) by whether or not an electron is present. But an electron itself has a binary property — whether or not its spin is "up" or "down." Researchers have now discovered a way to encode data with electron spin, potentially doubling memory with zero tradeoffs.
