Improvement of two‐step write scheme in complementary resistive switch array

Abstract

In this study, an improvement for two-step write scheme to reduce the resistance change in complementary resistive switch array is proposed. The authors change the amplitudes of write voltages and improve the scheme to three-step write. The disadvantages of the previous two-step write scheme are analysed. Compared with the traditional write scheme, the improved scheme can reduce resistance change about 68%, which does not need any other devices. The average power consumption for this write operation is lower. Through simulation, the feasibilities of the improved two-step write scheme are demonstrated.
