e report the first digital nonvolatile memory devices
fabricatedwithDNAsandDNA-mimickingbrushpolymers.
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-once-
read-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.
