  Non-Markovian quantum effects are typically observed in systems interacting
with structured reservoirs. Discrete-time quantum walks are prime example of
such systems in which, quantum memory arises due to the controlled interaction
between the coin and position degrees of freedom. Here we show that the
information backflow that quantifies memory effects can be enhanced when the
particle is subjected to uncorrelated static or dynamic disorder. The presence
of disorder in the system leads to localization effects in 1-dimensional
quantum walks. We shown that it is possible to infer about the nature of
localization in position space by monitoring the information backflow in the
reduced system. Further, we study other useful properties of quantum walk such
as entanglement, interference and its connection to quantum non-Markovianity.
