AbstractRatio-based encoding has recently been proposed for single-level resistive memory cells, in which the resistance ratio of a pair of resistance-switching devices, rather than the resistance of a single device (i.e. resistance-based encoding), is used for encoding single-bit information, which significantly reduces the bit error probability. Generalizing this concept for multi-level cells, we propose a ratio-based information encoding mechanism and demonstrate its advantages over the resistance-based encoding for designing multi-level memory systems. We derive a closed-form expression for the bit error probability of ratio-based and resistance-based encodings as a function of the number of levels of the memory cell, the variance of the distribution of the resistive states, and the ON/OFF ratio of the resistive device, from which we prove that for a multi-level memory system using resistance-based encoding with bit error probability x, its corresponding bit error probability using ratio-based encoding will be reduced to $$x^2$$ x 2 at the best case and $$x^{\sqrt{2}}$$ x 2 at the worst case. We experimentally validated these findings on multiple resistance-switching devices and show that, compared to the resistance-based encoding on the same resistive devices, our approach achieves up to 3 orders of magnitude lower bit error probability, or alternatively it could reduce the cell’s programming time and programming energy by up 5–10$$\times$$ × , while achieving the same bit error probability.

ZnMn2O4films for resistance random access memory (RRAM) were fabricated on p-Si substrate by magnetron sputtering. The effects of thickness onI-Vcharacteristics, resistance switching behavior and endurance characteristics of ZnMn2O4films were investigated. The ZnMn2O4films with a structure of Ag/ZnMn2O4/p-Si exhibit bipolar resistive switching behavior. With the increase of thickness of ZnMn2O4films from 0.83μm to 2.3μm, both theVONand the number of stable repetition switching cycle increase, but theRHRS/RLRSratio decrease, which indicated that the ZnMn2O4films with a thickness of 0.83μm has the biggestRHRS/RLRSratio and the lowestVONandVOFF, but the worst endurance characteristics.
