Abstract :
Phase Change Memory (PCM) technology is a promising candidate for the future non-volatile memory applications. Scaling of PCM into the sub-10 nm regime has been demonstrated using novel applications of nanofabrication techniques. PCM devices using solution-processed GeTe nanoparticles of diameter range 1.8-3.4nm has been demonstrated. Highly scaled (<;2nm) PCM cross-point device using carbon nanotube as the electrode is fabricated proving the scalability of PCM to ultra small dimensions. The use of PCM as a nanoelectronic synapse for neuromorphic computation is also demonstrated as an illustration of PCM application beyond digital memory.
