  The uncertainty principle is one of the key concepts in quantum theory. This
principle states that it is not possible to measure two incompatible
observables simultaneously and accurately. In quantum information theory, the
uncertainty principle is formulated using the concept of entropy. In this work
we consider the entropic uncertainty relation in the presence of quantum
memory. We study the dynamics of entropic uncertainty bound for a two-qubit
quantum system coupled to a spin chain with Dzyaloshinskii-Moriya interaction
and we investigate the effect of environmental parameters on the entropic
uncertainty bound. Notably, our results reveal that there exist some
environmental parameters which can be changed to suppress the entropic
uncertainty bound.
