Abstract
We report the first digital nonvolatile memory devices fabricated with DNAs and DNA-mimicking brush polymers. DNA-mimicking brush polymers were newly synthesized based on dielectric brush polyacrylates. Salmon testes and calf thymus DNAs were chosen as natural DNAs. Salmon testes and calf thymus DNA devices, as well as DNA-mimicking brush polymer devices revealed p-type unipolar write-onceread-many-times memory behaviors with low switching-on voltage and high ON/OFF current ratio. Such permanent memory characteristics were confirmed to originate from the charge trapping and hopping nature of nucleobase moieties. Overall, this study demonstrated that DNA and DNA-mimicking polymers are good candidate materials for the production of p-type permanent memory devices with high performance, high stability and low power consumption.
