Abstract
A semiconductor device includes a first driver circuit for supplying a first potential to a first power supply node of the sense amplifier, second and third driver circuits for supplying a second potential and a third potential to a second power supply node of the sense amplifier, and a timing control circuit for controlling operations of the first to third driver circuits. The timing control circuit includes a delay circuit for deciding an ON period of the third driver circuit. The delay circuit includes a first delay circuit having a delay amount that depends on an external power supply potential and a second delay circuit having a delay amount that does not depend on the external power supply potential, and the ON period of the third driver circuit is decided based on a sum of the delay amounts of the first and second delay circuits.
