英文摘要	True random number generator (TRNG) is a critical component in hardware security that is increasingly important in the era of mobile computing and internet of things. Here we demonstrate a TRNG using intrinsic variation of memristors as a natural source of entropy that is otherwise undesirable in most applications. The random bits were produced by cyclically switching a pair of tantalum oxide based memristors and comparing their resistance values in the off state, taking advantage of the more pronounced resistance variation compared with that in the on state. Using an alternating read scheme in the designed TRNG circuit, the unbiasedness of the random numbers was significantly improved, and the bitstream passed standard randomness tests. The Pt/TaOx/Ta memristors fabricated in this work have fast programming/erasing speeds of similar to 30 ns, suggesting a high random number throughput. The approach proposed here thus holds great promise for physically-implemented random number generation.; National Key R&D Program of China [2017YFA0207600]; Beijing Municipal Science & Technology Commission [Z161100000216148]; National Natural Science Foundation of China [61674006, 61421005]; '1000 Youth Talents Program' of China; SCI(E); ARTICLE; 45; 28
