Novel Nanostructures Give Boost to Phase Change Memory

Flash memory is that non-volatile (NV) memory that everyone believes is ripe to be displaced in mobile electronics. But instead it has remained remarkably resilient undergoing just enough incremental improvementsover the years to maintain its dominant position in the field.

Among the alternatives attempting to mount a commercial challenge to flash is phase-change random access memory (PCRAM or PRAM).  PRAM operates by heating a material in the memory cell that switches between a conductive crystalline phase and a resistive amorphous phase, imparting the binary characteristic necessary for memory.
