Abstract
An integrated circuit device may include a transmission driver and an equalizer. The transmission driver may be configured to, in response to a transmission control data, transmit an output signal to an outside through a signal line in a transmission operation that outputs the output signal to the outside, and provide termination resistance in a reception operation that receives an input signal from the outside through the signal line. The equalizer may be configured to, in response to an equalizer control data, amplify high-frequency components of the output signal in the transmission operation, and to provide termination resistance in the reception operation.
Claims16
An integrated circuit device comprising:
- a transmission driver configured to, in response to a transmission control data, transmit an output signal to an outside through a signal line in a transmission operation, and provide a termination resistance in a reception operation that receives an input signal from the outside through the signal line;
- and
- an equalizer configured to, in response to an equalizer control data, amplify high-frequency components of the output signal in the transmission operation, and provide the termination resistance in the reception operation.
An operation method of an integrated circuit device comprising an equalizer control circuit, a transmission driver, and an equalizer, the operating method comprising:
- receiving, by the equalizer control circuit, a data and a selection signal indicating a reception operation of the integrated circuit device;
- selecting, by the equalizer control circuit, as a first code, a second EQ code among a first EQ code corresponding to a pre-emphasis operation and the second EQ code corresponding to an on die termination (ODT) operation, in response to the selection signal indicating the reception operation;
- generating an equalizer control data, by the equalizer control circuit, by encoding based on the first code and the received data;
- outputting the generated equalizer control data to the equalizer;
- and
- providing termination resistance, by the equalizer, based on the equalizer control data.
