Graphite-based Selectorless RRAM: Improvable Intrinsic Nonlinearity for Array Applications

Abstract

Selectorless graphite-based resistive random-access memories (RRAM) have been demonstrated by utilizing the intrinsic nonlinear resistive switching (RS) characteristics, without additional selector or transistor for low-power RRAM array application. The low effective dielectric constant value (k) layer of graphite or graphite oxide is utilized, which is beneficial in suppressing sneak-path currents in crossbar RRAM array. The tail-bits with low nonlinearity can be manipulated by positive voltage pulse, which in turn can alleviate variability and reliability issues. Our results provide additional insights for built-in nonlinearity in 1R-only selectiveless RRAMs, which are applicable to low-power memory array, ultrahigh density storage, and in-memory neuromorphic computational configurations.
