摘要: | All-nonmetal resistive random access memory (RRAM) with a N+-Si/SiNx/P+-Si structure was investigated in this study. The device performance of SiNx developed using physical vapor deposition (PVD) was significantly better than that of a device fabricated using plasma-enhanced chemical vapor deposition (PECVD). The SiNx RRAM device developed using PVD has a large resistance window that is larger than 10(4) and exhibits good endurance to 10(5) cycles under switching pulses of 1 mu s and a retention time of 10(4) s at 85 degrees C. Moreover, the SiNx RRAM device developed using PVD had tighter device-to-device distribution of set and reset voltages than those developed using PECVD. Such tight distribution is crucial to realise a large-size cross-point array and integrate with complementary metal-oxide-semiconductor technology to realise electronic neurons. The high performance of the SiNx RRAM device developed using PVD is attributed to the abundant defects in the PVD dielectric that was supported by the analysed conduction mechanisms obtained from the measured current-voltage characteristics. |
