Quantum dot memory

Next time you have trouble with i/o performance, think about this: wouldn't it be great to fit a terabyte of non-volatile RAM onto a one square inch postage stamp, with write times of 6 nanoseconds? Soon quantum-dot memory may do just that for you. That's nearly as fast as regular DRAM, and around 1000 times faster than typical flash memory. Scientists even say they could eventually get the write time down to picoseconds. Scary or what?
