  We discuss super Schrodinger algebras with less supercharges from N=4
superconformal algebra psu(2,2|4). Firstly N=2 and N=1 superconformal algebras
are constructed from the psu(2,2|4) via projection operators. Then a super
Schrodinger subalgebra is found from each of them. The one obtained from N=2
has 12 supercharges with su(2)^2 x u(1) and the other from N=1 has 6
supercharges with u(1)^3,. By construction, those are still subalgebras of
psu(2,2|4). Another super Schrodinger algebra, which preserves 6 supercharges
with a single u(1) symmetry, is also obtained from N=1 superconformal algebra
su(2,2|1). In particular, it coincides with the symmetry of N=2
non-relativistic Chern-Simons matter system in three dimensions.
