Abstract
This paper focuses on the programming operation optimization of a HfO2-based Resistive RAM (RRAM) memory array for low power consumption application. We will show how the resistance window (RW) depends on the write/erase energy, and we will give directives to minimize the operating energy cost. In particular, the advantage of short pulse over low current operation is demonstrated. We also link the array size with the programming energy. Gain with smart programming scheme is also discussed. Eventually we explain how the operating energy impacts on the maximum transfer rate (RT) achievable in a product. © 2017 IEEE.
