Abstract
According to one embodiment, a level shift circuit includes first through fourth transistors, a control circuit, and first and second generating circuits. The control circuit outputs a first voltage obtained by level-shifting an input voltage to a first terminal. The first transistor supplies a first electric current to the control circuit for outputting the first voltage to the first terminal. The second transistor increases the first electric current. The first generating circuit generates a first pulse signal for controlling the second transistor. The third transistor supplies a second electric current to the first terminal for generating a second voltage corresponding to a first supply of a low-potential side. The fourth transistor increases the second electric current. The second generating circuit generates a second pulse signal for controlling the fourth transistor.
