ABSTRACT:
An exemplary aspect of the present invention is a sense amplifier having a power supply voltage of 1.2 V or lower and amplifying a potential difference between a bit line pair, a first transistor supplying the power supply voltage to the sense amplifier, a second transistor supplying a low potential side voltage to the sense amplifier, and a control circuit controlling the first transistor to be a conduction state before the second transistor is set to the conduction state or at the same time when the second transistor is set to the conduction state.
