Abstract
A level conversion circuit for converting a first signal at a lower power source side into a second signal at a higher power source side, which is higher than the lower power source, includes first and second transistors provided at a ground side and controlled by the first signal and an inverted signal there of; third and fourth transistors gates and drains of which are cross-connected, provided at the higher power source side and connected to the first and second transistors respectively; and an initialization circuit for, at a higher power voltage rise time, reducing (or raising), along a current path, a level of either a first node located between the first and third transistors, or a second node located between the second and fourth transistors, to a ground voltage (or to a voltage of the higher power source).
