摘要:
A sense amplifier according to the present invention for detecting a potential difference of signals input to a first input terminal and a second input terminal, includes a first means for applying voltages corresponding to threshold voltages of first and second transistors to gate-source voltages of the first and second transistors, and a second means for transferring signals input to the first and second input terminals to gates of the first and second transistors. In this case, a threshold variation of the first and second transistors is corrected.
