Abstract
A semiconductor memory device includes a memory cell, a signal line on which a potential responsive to data read from the memory cell appears, a potential detecting circuit which outputs a detection signal in response to detecting that the potential on the signal line exceeds a predetermined potential, and a sense amplifier which starts amplifying the potential on the signal line in response to the detection signal.
