Abstract
A data output buffer may be provided. The data output buffer may include a pull-up circuit configured to output a pull-up feedback signal by pull-up driving an output node. The data output buffer may include a pull-up driver configured to output the pull-up drive signal by driving a pull-up signal, and selectively activate the pull-up drive signal based on the pull-up feedback signal. The data output buffer may include a pull-down circuit configured to output a pull-down feedback signal by pull-down driving the output node based on a pull-down drive signal. The data output buffer may include a pull-down driver configured to output the pull-down drive signal by driving a pull-down signal, and selectively activate the pull-down drive signal based on the pull-down feedback signal.
