Abstract
A semiconductor memory device includes a reset signal generating unit configured to generate a reset control signal by delaying a column command signal by an amount of time varying proportional to an operational frequency. A pulse width determination unit is configured to determine a pulse width of a column selection signal in response to the column command signal and the reset control signal. An address decoding unit is configured to generate the column selection signal corresponding to a corresponding column address in response to an output signal of the pulse width determination unit.
