In Memory of ... Memory

When our own memory gets filled up, we tend to write more things down then we used to. I have notes and lists about notes and lists for important things to remember. But what happens when our PDA, iPod, or cell phone memory hits a wall. In the usual case, we buy a new one and attempt to transfer applications and data from one device to another. But computer engineers at Northwestern University and NEC Laboratories America, Inc. give us some options. They developed technology that doubles the usable memory on cell phones and other embedded systems without any changes to hardware or applications.
