    • There is provided a multi-port memory device, which is capable of minimizing a layout area of a global data bus connection circuit while maintaining a line arrangement of global data buses. The multi-port memory device includes a plurality of unit global data bus connection circuits for selectively connecting first and second global data buses, each of which includes a plurality of lines. The plurality of unit global data bus connection circuits are arranged in M×N matrix (M and N are integers greater than or equal to two). The respective unit global data bus connection circuits are overlapped with line axis of the corresponding first and second global data buses and adjacent line axis. Loads to be driven by the control signal of the global data bus connection circuit can be reduced and skew of the pipe register control signal can be minimized.

    • There is provided a column repair technology of a semiconductor memory device. The semiconductor memory device includes: a normal bus connection part for transmitting/receiving data between global data buses and local data buses of each bank; a redundant bus connection part for transmitting/receiving data between global data buses and local data buses of each bank; a fuse set having a physical position information of a fail column; and a switching part for selectively connecting outputs of the normal bus connection part and the redundant bus connection part to the global data buses, which corresponds to the fail column, in response to the physical position information of the fail column. The column redundancy scheme can be applied to semiconductor memory devices having such a structure that a lot of column selection lines are enabled with respect to one column address and can also be applied to a case when a fail column address is not present. Therefore, the redundancy efficiency can be improved and an increase of the chip area can be prevented.
