flash memory stacked higher

To me, the introduction of the USB stick (flash drive) was the point where the boundaries between technology and magic started to blur. How on Earth do you squeeze a 2 Gbyte memory into that ?

Now, scientists in Korea have developed a way of multiplying the capacity of flash memory devices, using stacked layers of nanoparticles. Read my story

here.

The story also gave me a chance to catch up with the fast-moving technology/magic boundary and to understand (for a fleeting moment) what a flash memory is and how it works. Don't ask me now, though, the moment has passed and I have a new story to write up.
