Abstract
The inventive concept provides semiconductor memory modules and methods of fabricating the same. The semiconductor memory module may include a module board having a first surface and a second surface opposite to the first surface, and memory chips mounted directly on the module board by a flip-chip bonding method. Each of the memory chips may include a passivation layer disposed on a rear surface of each of the memory chips, and the passivation layer may have a color different from a natural color of single-crystalline silicon.
