Noncommutative torus compactification of Matrix model is shown to be a
direct consequence of quantization of the open strings attached to a
D-membrane with a non-vanishing background B field. We
calculate the BPS spectrum of such a brane system using both string
theory results and DBI action. The DBI action leads to a new
transformation property of the compactification radii under the
SL (2,Z)N transformations.
