    (IEEE, 2017) Vourkas, Ioannis; Gómez Luna, Jorge Antonio; Abusleme Hoffman, Ángel Christian; Vasileiadis, Nikolaos; Sirakoulis, Georgios C.; Rubio, Antonio
    The maximum exploitation of the favorable properties and the analog nature of memristor technology in future nonvolatile resistive memories, requires accurate multi-level programming. In this direction, we explore the voltage divider (VD) approach for highly controllable multi-state SET memristor tuning. We present the theoretical basis of operation, the main advantages and weaknesses. We finally propose an improved closed-loop VD SET scheme to tackle the variability effect and achieve <;1% tuning precision, on average 3x faster than another accurate tuning algorithm of the recent literature.
