In this paper we consider D = 4 NCSYM theories with 8 supercharges. We stud
y these theories through a proper type IIA (and M-theory) brane configurati
on. We find the one loop beta function of these theories and show that ther
e is an elliptic curve describing the moduli space of the theory, which is
in principle the same as the curve for the commutative counter-part of our
theory. We study some other details of the dynamics by means of this brane
configuration. (C) 2000 Elsevier Science B.V. All rights reserved.
