1. A semiconductor memory device, comprising:
a global input/output line;
a first global core line;
a second global core line;
a global core line controller disposed between the first global core line and the second global core line;
a first bank coupled to the global core line controller through the first global core line; and
a second bank coupled to the global core line controller through the second global core line,
wherein the global core line controller includes
a read/write strobe signal activating unit configured to receive read/write information and a strobe signal for a column operation to output a read strobe signal and a write strobe signal, the read strobe signal and the write strobe signal being activated in a read operation and a write operation, respectively.
