Abstract
A signal transfer circuit for receiving a first signal to transfer the received first signal as a second signal by using an operating power source having a second voltage level, the signal transfer circuit may include: a first setting circuit; and a second setting circuit, the first signal may swing between a first voltage level and a ground level, and the second signal may swing between a third voltage level and the ground level, the first setting circuit may be configured to set the third voltage level to be same as the second voltage level, when the first voltage level is higher than the second voltage level, and the second setting circuit may be configured to set the third voltage level to be same as the first voltage level, by detecting when the first voltage level is lower than or equal to the second voltage level.
