RELAYING CIRCUIT, INFORMATION PROCESSING DEVICE, AND RELAYING METHOD

摘要

A relaying circuit is provided between a first circuit driven at a first voltage and a second circuit driven at a second voltage different from the first voltage and relays signal transmission between the first circuit and the second circuit. The relaying circuit comprises a waveform shaping circuit which shapes the waveform of the second voltage so that the change of the second voltage becomes sharper to obtain a shaped-waveform voltage, and a buffer circuit which is driven at the first voltage, to which the shaped-waveform voltage obtained by the waveform shaping circuit is inputted as a control signal, and which interrupts the signal transmission when the shaped-waveform voltage becomes a predetermined value or lower.
