Semiconductor apparatus capable of preventing occurrence of multiple reflection, driving method, and setting method thereof

摘要

A semiconductor apparatus comprises a resistor formed in a driver to connect a driving device to a transmission line connecting the driver to a receiver. The resistor has resistance considerably larger than on-state resistance of the driving device on condition that the resistor matches output impedance of the driver with impedance of the transmission line. The transmission line has length decided so that a reflected wave from a receiver-side end of the transmission line reaches the driver while a driving signal supplied to the driver has a logical high or low level.
