| 发明名称 | Operating method of input/output interface | ||
| 摘要 | A method of operating an input/output interface includes selecting one of a plurality of output driver circuits according to a mode selection signal, and outputting a data signal using the selected one of the plurality of output driver circuits. Another method of operating an includes generating a mode selection signal based on a received command signal, and controlling an on-die termination (ODT) circuit included in the input/output interface according to the mode selection signal. Another method of operating an includes generating a mode selection signal based on a received command signal, and controlling an ODT circuit included in the input/output interface according to the mode selection signal. | ||

| 主权项 | 1. A method of operating an input/output interface comprising: selecting, by an output block of the input/output interface, one of a plurality of output driver circuits according to a mode selection signal, the mode selection signal being a control signal for controlling an on-die termination (ODT) circuit included in the input/output interface, the mode selection signal indicating an operation mode for one of a high speed operation and a low speed operation and the selecting selects the one of the plurality of output driver circuits based on whether the mode selection signal indicates the high speed operation or the low speed operation; and outputting a data signal using the selected one of the plurality of output driver circuits. | ||
