Resistive memories (RRAM) are attracting a wide interest as candidates for the next generation memory technology, in particular for embedded and, more generally, for low power applications like IoT. However, their variability still remains a concern as the latter has been proven to be an intrinsic feature linked to the filamentary switching mechanism. In this paper we will review some recent key results by our and other groups that show the fundamental variability limits of the HfO2-based technology and some possible alternatives.

Abstract
Resistive memories (RRAM) are attracting a wide interest as candidates for the next generation memory technology, in particular for embedded and, more generally, for low power applications like IoT. However, their variability still remains a concern as the latter has been proven to be an intrinsic feature linked to the filamentary switching mechanism. In this paper we will review some recent key results by our and other groups that show the fundamental variability limits of the HfO2-based technology and some possible alternatives.File in questo prodotto:
