Woo Hoo

By Mitch Berg

20 years ago when I suggested this concept, people got a good laugh.

Who’s laughing now, huh?

Flash memory, with no moving parts to break or wear down, is the data storage technology of choice for devices such as iPods and digital cameras. But phase-change RAM is set to overtake flash entirely—it uses a chemical found in rewritable discs, which is alternately heated and cooled to store data. The result is memory that’s 30 times faster than flash, with more than 10 times the life span.

Granted, my idea was more akin to “dude, what if our universe if just an atom within a larger universe…” rather than a treatise on electrical engineering.

But still.
