Abstract
A semiconductor memory device includes a memory cell, a bit line connected to the memory cell, and a sense amplifier. The sense amplifier is connected to the bit line, receives a first control signal, and detects and amplifies a bit line signal of the bit line. The sense amplifier includes a precharge device that is turned on or turned off based on a read control signal, and a transistor output unit that outputs an output voltage based on the bit line signal when the precharge device is turned off.
