| 发明名称 | Data transmission circuits and system having the same | ||
| 摘要 | Data transmission circuits are provided. The data transmission circuit includes a control signal generator and an output driver. The control signal generator generates a pull-up control signal and a pull-down control signal by using a count signal that changes in response to a clock signal during a drive control period. The output driver receives an internal data signal and drives a transmission data signal in response to the pull-up control signal and the pull-down control signal. | ||

| 主权项 | 1. A data transmission circuit comprising: a control signal generator configured to generate a pull-up control signal and a pull-down control signal by using a count signal that changes in response to a clock signal during a drive control period; and an output driver configured to receive an internal data signal and to drive a transmission data signal in response to the pull-up control signal and the pull-down control signal, wherein the drive control period may be set to a period when an impedance calibration test is being carried out. | ||
