Abstract
A negative power supply circuit is connected via an NMOS transistor to a node receiving ground potential in a sense amplifier. A one shot pulse generation circuit provides a one shot pulse signal to the gate of the NMOS transistor. The NMOS transistor is turned on when a one shot pulse signal is applied to connect the negative power supply circuit to the node. This causes the potential of the node to be lowered to a negative potential. As a result, increase in the potential at the ground side of the sense amplifier caused by an interconnection resistance in the ground interconnection is suppressed. Therefore, variation in the potential received by the sense amplifier due to interconnection resistance can be suppressed.
