In this paper, we consider the lattice SchrSdinger equations iqn(t) = tan π(na+x)qn(t) +ε(qn+1(t) + qn-1(t)) +δVn(t)|qn(t)|2τ-2qn(t),with a satisfying a certain Diophantine condition, x∈ R/Z, and t- = 1 or 2, where vn(t) is a spatial localized real bounded potential satisfying |vn(t)| Ce-plnl. We prove that the growth of H1 norm of the solution {qn(t)}n∈Z is at most logarithmic if the initial data {qn(0)}n∈Z ∈ H1 for e sufficiently small and a.e. x fixed. Furthermore, suppose that the linear equation has a time quasi-periodic potential, i.e.,
