Abstract
A semiconductor memory device includes a pair of local input/output (IO) lines, a global IO line, a local driver configured to pull up/down voltage levels of the first and second local IO lines in response to input data, a global driver configured to pull up/down a voltage level of the global IO line in response to input data, and a data IO control block configured to transport output data from the local IO lines to the global driver and input data from the global IO line to the local driver.
