  The uncertainty of measurement on a quantum system can be reduced in presence
of quantum memory [M. Berta et. al. Nature Phys. {\bf 6}, 659 (2010)]. By
measurement on quantum memory, some information (non-classical information) is
inaccessible, hence, it limits the lower bound of entropic uncertainty
relation. In the present work, we improve the lower bound of entropic
uncertainty relation in presence of quantum memory by considering
inaccessibility of non classical correlation at Bob side and also compare the
lower bound given by M. Berta et. al. and our prescription for two different
kind of shared bipartite state.
