| 发明名称 | Semiconductor device for performing preemphasis operation | ||
| 摘要 | A semiconductor device includes: a main driving unit configured to receive an output data and to drive the received data to a data output pad; a pre-emphasis data generation unit configured to compare a delayed data obtained by delaying the output data by one data period with the output data, to delay the comparison result by one data period, and to output the delayed data as pre-emphasis data; and a pre-emphasis driving unit configured to receive the pre-emphasis data and to drive the received data to the data output pad. | ||

| 主权项 | 1. A semiconductor device comprising: a main driving unit configured to receive an output data and to drive the received data to a data output pad; a pre-emphasis data generation unit configured to compare a delayed data obtained by delaying the output data by one data period with the output data, to delay a comparison result by one data period, and to output a delayed comparison result as pre-emphasis data; and a pre-emphasis driving unit configured to receive the pre-emphasis data and to drive the received data to the data output pad, wherein the pre-emphasis driving unit operates when the data period where the output data maintain same logic level is maintained during two or more data periods. | ||
