  PHENIX measures leptons at mid and forward rapidities and extracts leptons
resulting from semi-leptonic decays of heavy quarks. We present PHENIX results
related to heavy quark production, specifically the invariant cross section of
the non-photonic single electrons produced at midrapidity in p+p and d+Au
collisions at sqrt(sNN) = 200 GeV. The measured cross section for {\it p+p}
collisions is compared with the NLO prediction, and a possible excess over the
prediction is noted. The measured cross section for {\it d+Au} collisions
scales with the number of colliding nucleon pairs from the {\it p+p} spectra.
