Abstract
A semiconductor integrated circuit has a word line, a pair of bit lines, a memory cell disposed on an intersection of the word line and the pair of bit lines, a precharge circuit for precharging the pair of bit lines at a first voltage, and a sense amplifier circuit for amplifying a potential difference of the pair of bit lines at a second voltage. The first voltage is substantially equal to an on voltage of the sense amplifier circuit, the on voltage being obtained by adding an offset voltage of the sense amplifier circuit to an on voltage of a transistor constituting the sense amplifier circuit, or the first voltage is a voltage between the on voltage of the sense amplifier circuit and the second voltage.
