We construct type II A brane configuration of N=(4,4) supersymmetric two
dimensional gauge theory with gauge group U(1) and Nf hypermultiplets in
the fundamental representation. By lifting to M-theory (strong coupling), we
can see the origin of the R-symmetry enhancement of the Coulomb branch. One
can also find two theories which become equivalent at strong coupling.
