(a) The relationship of log (RLRS) and probability density (%) with log-normal distribution. Here the number of samples measured is 100 (%). (b) The relationship of log (RHRS) and probability density (%) with log-normal distribution. Here the number of samples measured is 100. (c) The failure map of the non-ideal 400 × 256 crossbar array consisting of the obtained RLRS and RHRS. The defective devices were randomly distributed and the failure percentage of the RRAM was assumed 10%.
