Multilevel memristive memory with resistive networks. Multilevel memristive memory with resistive networks arxiv. A method to utilize the memristor as a multilevel memory has been proposed. To have a keepsake that will stand the test of time so that you can time travel back and relive these amazing moments 30 years from now. Using a memristor as an mlc introduces fault mechanisms that cannot occur in typical twolevel memory cells. In this paper, a memory cell, which is with two antiparallel memristors and two transistors 2t2m, is proposed to achieve memristorbased 3bit storage while removing the use of reference resistors and reducing the number of comparators, thus enabling ultradense nonvolatile memristor memory. There are several roadblocks in the practical use of memristors for multilevel memory. Although this paper introduced an implementation for multilevel adders using hp memristor model in low frequency, the same idea can be applied for any reciprocal memristor model with fast switching time to build faster systems. Memistor has multilevel resistance property that can be controlled by the voltage or current applied across the device as a function of time and can be programmed to any resistance level between a maximum possible resistance and minimum resistance 22. In this paper, memristor based quinary half adder is introduced. To develop a memristor based multilevel memory, the earlier designs widely used reference resistance arrays 23, crossbar technology 24. Nonvolatile multilevel resistive switching memory cell.
