Traditional digital processing approaches are based on semiconductor transistors,which suffer from high power consumption,aggravating with technology node scaling.To solve definitively this problem,a number of emerging non-volatile nanodevices are under intense investigations.Meanwhile,novel computing circuits are invented to dig the full potential of the nanodevices.The combination of non-volatile nanodevices with suitable computing paradigms have many merits compared with the complementary metal-oxide-semiconductor transistor(CMOS)technology based structures,such as zero standby power,ultra-high density,non-volatility,and acceptable access speed.In this paper,we overview and compare the computing paradigms based on the emerging nanodevices towards ultra-low dissipation.
