Abstract
A sense amplifier includes a first P channel MOS transistor connected between a power source terminal and a bit line, and a CMOS inverter for inverting the logic level of the potential in the bit line. The sense amplifier further includes a second N channel MOS transistor connected in series to the first P channel MOS transistor between the power source terminal and the bit line. The second N channel MOS transistor is switch-controlled by an output signal of a CMOS inverter. When in an off state, the second N channel MOS transistor prohibits the first P channel MOS transistor from transferring a power source potential to the bit line. When in an on state, the second N channel MOS transistor allows the first P channel MOS transistor to transfer the power source potential to the bit line.
