"material (M) state-based shift register... amorphous state, fully crystalline state, partially crystallized state and primed state of phase-change material operate device...  as memory, can be switched from disordered glass state to crystalline state 1.9 ns pulses...  resetting energy 2 pJ... shift register can be switched between serial-in–serial-out mode to serial-in–parallel-out mode, with single cell, and exhibit many resistance levels... could be used to design a wide range of high-performance electronic systems"
