Original Abstract Submitted
A level shift circuit includes: a level information output circuit configured to output level information on an input signal; a latch circuit configured to operate between a first voltage and a reference voltage lower than the first voltage to latch the output of the level information output circuit; and a voltage controller configured to raise the first voltage to a first set value after completion of latching by the latch circuit, then, when the first voltage reaches the first set value, to raise the reference voltage to a second set value, and then, after raising the reference voltage to the second set value, to raise the first voltage to a third set value.
