Abstract
A semiconductor memory device includes a bitline sensing amp detecting and amplifying data of a pair of bitlines from a memory cell, a column selecting unit transmitting the data of the pair of bitlines to a pair of local datalines in response to a column selecting signal, a dataline precharging unit precharging the pair of local datalines to a precharging voltage level in response to a precharging signal, and a dataline sensing amp detecting and amplifying data transmitted to the pair of local datalines. The dataline sensing amp includes a charge sync unit discharging the pair of local datalines at the precharging voltage level in response to a first dataline sensing enabling signal and data of the pair of local datalines, and a data sensing unit transmitting data of the pair of local datalines to a pair of global datalines in response to a second dataline sensing enabling signal.
