Abstract
A data output buffer includes a first driver configured to drive a data input/output (I/O) pad according to an input signal and allow data drivability to be controlled according to an impedance calibration code and a second driver configured to perform a de-emphasis operation on the data I/O pad and allow de-emphasis drivability to be controlled according to the impedance calibration code.
Claims7
A data output buffer comprising:
- a first driver configured to drive a data input/output (I/O) pad according to an input signal and allow data drivability to be controlled according to an impedance calibration code;
- and
- a second driver configured to directly receive emphasis signals and the impedance calibration code, perform a de-emphasis operation on the data I/O pad and allow de-emphasis drivability to be controlled according to the impedance calibration code.
