Slave device, system including master device and slave device, method for operating the same, and chip package

摘要

A slave device communicating with a master device includes a transmission unit configured to transmit a signal to the master device through a communication channel, a calibration unit configured to measure a flight time of a calibration signal which is transmitted to the master device and fed back through a calibration channel coupled to the master device, and a transmission delay unit configured to delay the signal transmitted from an internal circuit of the slave device to the transmission unit by a delay value determined according to the measurement result of the calibration unit.
