As the size of the circuitry gets ever smaller, EETimes is going with a prediction that technologies like trapped charge and phase change memories will become the dominant form of flash memory. Not only that, they're thinking the tide could change as early as five years from now.

"Phase change memories store bits by switching a chalcogenide material between amorphous and crystalline states. Currently, the vast majority of trapped charge memories are used as NOR flash for code storage, and accounted for 15.7 percent of the NOR flash market in 2006."
