DATA OUTPUT BUFFER WITH FAST INPUT/OUTPUT TRANSITION

摘要

a full-up current searching means for outputting and comparatively amplifying a potential of the output and a first reference potential generated when the control signal for the full-up driver means is enabled; a first logic means for performing a logic operation of an output signal generated from the full-up current searching means, and outputting the result to the full-up driver means; a full-down current searching means for outputting and comparatively amplifying the potential of the output and a second reference potential generated when the control signal for the full-down driver means is enabled; and a second logic means for performing a logic operation of an output signal generated from the full-down current searching means, and outputting the result to the full-down driver means.
