Abstract
This invention provides a signal transfer technique capable of realizing stable high rate data transfer and the reduction of a layout area. A system (semiconductor device) for realizing a high rate data transfer circuit method includes: a transmission circuit which consists of a normal signal transmitter and a receiving amplifier starting signal transmitter; a receiving circuit which consists of a receiving amplifier and a receiving amplifier starting signal receiver; a normal signal line and a receiving amplifier starting signal line connected between the transmission circuit and the receiving circuit; and the like. The normal signal transmitter includes a circuit which changes an output level for a specific period in accordance with the level of a normal signal and a circuit which controls the normal signal line to allow the normal signal line to function between VDD and VSS. The receiving amplifier includes a capacitance and a circuit which fetches a voltage of the capacitance at predetermined change timing of a control signal and then outputs a signal based on the fetched voltage of the capacitance. The receiving amplifier consists of a chopper comparator, and the normal signal line consists of a single transmission path.
