  We investigate the gluonic probe to the nucleon-nucleon short range
correlation (SRC) in nucleus through heavy flavor production in deep inelastic
scattering (DIS). The relevant EMC effects of $F_2^{c\bar c}$ structure
function will provide a universality test of the SRCs which have been
extensively studied in the quark-channel. These SRCs can also be studied
through the sub-threshold production of heavy flavor in $eA$ collisions at the
intermediate energy electron-ion collider, including open Charm and $J/\psi$
($\Upsilon$) production.
