Transient memories,which can physically disappear without leaving traceable remains over a period of normal oper-ation,are attracting increasing attention for potential applications in the fields of data security and green electronics.Resis-tive random access memory(RRAM)is a promising candidate for next-generation memory.In this context,biocompatible t-carrageenan(t-car),extracted from natural seaweed,is introduced for the fabrication of RRAM devices(Ag/t-car/Pt).Taking advantage of the complexation processes between the functional groups(C-O-C,C-O-H,et al.)and Ag metal ions,a lower migration barrier of Ag ions and a high-speed switching(22.2 ns for SET operation/26 ns for RESET opera-tion)were achieved,resulting in an ultralow power consumption of 56 fJ.And the prepared Ag/t-car/Pt RRAM devices also revealed the capacities of multilevel storage and flexibility.In addition,thanks to the hydrophilic groups of t-car molecule,the RRAM devices can be rapidly dissolved in deionized(DI)water within 13 minutes,showing excellent transient char-acteristics.This work demonstrates that t-car based RRAM devices have great potential for applications in secure storage applications,flexible electronics and transient electronics.
