Abstract
A data driver is presented in which the data driver includes a termination/pull-up driver and a pull-down driver. The termination/pull-up driver is configured to perform a termination operation and a pull-up operation at the same time for a data output terminal during an active interval of a semiconductor memory. The pull-down driver is configured to be activated when the semiconductor memory performs a read operation, and configured to pull down the output terminal in response to a level of an input data.
Claims9
A data driver, comprising:
- a termination/pull-up driver configured to simultaneously perform a termination operation and a pull-up operation for a data output terminal during an active interval of a semiconductor memory;
- and
- a pull-down driver configured to be activated when the semiconductor memory performs a read operation, and configured to pull down the output terminal in response to a level of an input data.
A data driver, comprising:
- a first driver configured to terminate a data output terminal with a predetermined resistance value in response to a termination control signal;
- and
- a second driver configured to pull down the data output terminal in response to a level of a output control signal and in response to a level of an input data,
- wherein the termination control signal is activated regardless of a read operation interval and a write operation interval and the output control signal is activated during the read operation interval.
