ABSTRACT:
A cell core unit and its peripheral circuit are driven by a relatively low voltage power supply. A constant voltage that does not depend on the power supply voltage is provided as a boosted voltage (VBOOST) to be supplied to a control signal for a word line of the cell core unit. A sense amplifier amplifies a higher voltage level of a bit line to the power supply voltage. Then, a circuit for generating a signal for defining the transition timing and/or the pulse width of a control signal from the peripheral circuit to the cell core unit performs signal delay using a delay circuit having a characteristic in which a delay time thereof decreases with reduction of the provided power supply voltage.
