| Abstract(in English) | We propose a memristor-based STDP synaptic device having an asymmetric time window. This device consists of a bipolar resistive-RAM (ReRAM), a capacitor, four nMOSFETs, and two pMOSFETs. First, we review fundamental characteristics of bipolar ReRAMs as well as the behavioral model that we use in this study. We also introduce our preceding study with respect to the development of memristive STDP devices having a causal role of a presynaptic neuron in driving a postsynaptic one. In this paper, we extend the original STDP synaptic device. Through extensive SPICE simulations, we demonstrate that conductance of our STDP device is certainly modulated (increased, decreased, and held) by the input spike timing, and that the proposed device plays causal and anti-causal roles in the synaptic plasticity. |
