Abstract: A bitline sense amplifier includes an amplifier circuit having a plurality of PMOS elements and a plurality of NMOS elements, a first switch circuit supplying a first power supply voltage to the plurality of PMOS elements, and a second switch circuit supplying one of a second power supply voltage, lower than the first power supply voltage, a first boost voltage higher than the second power supply voltage, and a second boost voltage, lower than the second power supply voltage, to the plurality of NMOS elements. The second switch circuit sequentially applies the first boost voltage, the second boost voltage, and the second power supply voltage to the plurality of NMOS elements based on an execution of a read operation.
