As a noncharge-based device, the intrinsic RRAM device is immune to single-event effects. However, single-event upset (SEU) due to the MOSFET in the one-transistor-one-RRAM (1T1R) array can be observed. A novel methodology, which can be easily integrated to the other memory system components, is proposed in this paper to detect and correct SEU in 1T1R RRAM memory array. Using the HfOx 1T1R RRAM array as an example, our simulation results show that, for an 8-Gb memory array, the proposed technique can detect and fix the soft errors induced by the heavy ion strikes with 0.66% increase in the chip area. Also, the suggested methodology minimally increases the energy consumption of the read and write operations by 0.2% and 0.1%, respectively.Read More
