摘要：
A column selection signal generator of a semiconductor memory device is configured to maintain a predetermined pulse width of a column selection signal regardless of change in process and external conditions by selectively using a self-generated pulse signal and a pulse signal generated by an external clock signal. The column selection signal generator comprises a command combination unit, a pulse generating unit, a comparison unit and a selection unit.
