Abstract
In a sense amplifier circuit, a CMOS inverter is connected to a power supply voltage and inverts and amplifies a voltage on a digit line connected to a selected memory cell of a memory cell section to generate a gate control signal. The first transistor is connected to the digit line and controls current flowing through the digit line in response to the gate control signal. A data of the selected memory cell is outputted from an output of the first transistor. A stabilizing section stabilizes an operation of the CMOS inverter such that a same operation of the CMOS inverter can be performed independent from change of the power supply voltage.
