Apparatus and methods for generating a column select line signal in semiconductor memory device

摘要

An apparatus for generating a column select line signal in a semiconductor memory device includes a column select line signal generator configured to generate a column select line signal in response to a column select line enable signal. The column select line signal has a first pulse width when the column select line signal generator is in a first operational mode and a second pulse width when the column select line signal generator is in a second operational mode. The second pulse width is longer than the first pulse width.
