1. A storage device, comprising:
a port, the port configured to:
transmit a first pulse signal through a transmission line,
receive a value of a first parameter through the transmission line, the first parameter being derived based on a duty ratio of the first pulse signal,
transmit a second pulse signal through the transmission line, and
receive a third pulse signal through the transmission line;
a first register configured to store the value of the first parameter;
a first correction circuit configured to adjust a duty ratio of the second pulse signal according to the value of the first parameter stored in the first register; and
a calibration processor configured to:
measure a pulse width of the third pulse signal, and
transmit the measured pulse width of the third pulse signal through the transmission line.
