摘要
In this study, we studied the effect of Al2O3 layer insertion on InGaZnO (IGZO) memristors by fabricating two kinds of crossbar arrays according to the presence or absence of the Al2O3 layer. It was confirmed that the asymmetric current-voltage (I-V) characteristics come from the bias-polarity-dependent Schottky barrier and improving the symmetry of the I-V properties plays an important role in programming the array. The on/off ratio and endurance characteristics of the device are improved by the inserted Al2O3 layer due to the voltage divide by high resistance of the layer. In addition, a pattern classification is experimentally verified in a 10 × 10 fabricated memristor crossbar array and the improvement of classification rate and power consumption by the insertion of the Al2O3 layer is discussed with binarized weight values.
