ABSTRACT:
A semiconductor memory device includes data transmission devices for transmit data in synchronization with each other. The semiconductor memory device includes a plurality of data transferring unit, a first control unit, a multiplexing unit, and a second control unit. The plurality of data transferring unit transfers data to a plurality of global lines. The first control unit controls the plurality of data transferring unit in response to a column select signal to select a column of a memory cell. The multiplexing unit multiplexes the data transferred to the plurality of global lines. The second control unit controls the multiplexing unit, wherein the second control unit synchronizes the column select signal with a column address signal having a column address information of the memory cell.
