Field of the Invention The present invention relates to a sense amplifier of a semiconductor memory device, wherein the sense amplifier is divided into three parts, and then the output of each part is operated at a potential slightly lower than the potential minus the threshold voltage of the transistor at the power supply potential or slightly higher than the threshold voltage. By operating at a potential, it is a technology for a sense amplifier that realizes a fast operating speed with the lowest power consumption.
