In this study, resistive random access memory (ReRAM) devices are fabricated using solution-processable sulfur-doped GeO 2 (GeO 2:S) on flexible substrates. The Al/GeO 2:S/Au ReRAM devices exhibit the unipolar resistive switching behavior with an on/off ratio of more than 10 7 and the memory characteristics are retained after 10 4 s. The memory characteristics are unaffected by strains, even after the continuous substrate bending test for 10 3 cycles.
