Engineers visualize electric memory as it fades

MADISON - While the memory inside electronic devices may often be more reliable than that of humans, it, too, can worsen over time.

Now a team of scientists from the University of Wisconsin-Madison and Argonne National Laboratory may understand why. The results are published in the early online edition (May 23) of the journal Nature Materials.

To create a detailed picture of how the atoms rearrange themselves inside an operating device during each electrical pulse, the researchers used the Advanced Photon Source - the country's most brilliant source of X-rays for research, located at the Argonne N......

Because previous researchers have not peeked inside working ferroelectric materials to understand their arrangement of atoms - key to the ability to recall information - the reasons why switching eventually stops had not been clearly identified.

"The electronic memory is stored in the structure of atoms, and that's why it's so i......
