  By using the effective non-Markovian measure [H.P. Breuer, E.M. Laine, J.
Piilo, Phys. Rev. Lett. 103, 210401 (2009)], we investigate non-Markovian
dynamics of a pair of two-level atoms (TLAs) system, each of which interacting
with a local reservoir. We show that subsystem dynamics can be controlled by
manipulating the coupling between TLAs, temperature and relaxation rate of the
atoms. Moreover, the correlation between non-Markovianity of subsystem and
entanglement between the subsystem and the structured bath is investigated, the
results show that the emergence of non-Markovianity has a negative effect on
the entanglement.
