Popis:	The spike-timing-dependent-plasticity (STDP) is considered to be the basic function for the synapse device to simulate biological activities of the brain. In this paper, we demonstrate four standard STDP forms with nanosecond timescale based on the analog property of RRAM. An operation scheme to achieve diverse STDP rules is proposed according to the relationship between conductance change and the applied voltage of pulses. The diverse ultra-fast STDP rules are realized experimentally in fabricated Al2O3/ HfO2-based RRAM. The maximum weight change is up to 300% under nanosecond timescale pulses. Moreover, the nonvolatile characteristic of the device enables long-term potentiation and depression.
