ABSTRACT:
Disclosed herein is a printed circuit board facilitating expansion of number of memory modules and memory system including the same. The printed circuit board of the present invention includes a plurality of slots and a plurality of controller terminals. Each of slots disposed in locations ranging from a 2n−1+1th location to a 2nth location with respect to the controller terminals includes 2k−nmodule terminals connected to the module terminals of slots ranging from the slot disposed in the first location to a slot disposed in a 2n−1th location; wherein, in the printed circuit board and memory system including the printed circuit board according to the present invention, dummy modules are not required to expand the number of memory modules. Further, according to the printed circuit board of the present invention, the expansion of the number of memory modules is facilitated.
