Abstract
A semiconductor device comprises a sense amplifier circuit amplifying a signal transmitted through the bit line, first/second data lines transmitting the signal amplified by the sense amplifier circuit, a read amplifier circuit driven by a first voltage and amplifying the signal; first/second switch circuits controlling connection between the above components, first/second voltage setting circuits setting the second/third data lines to a second voltage lower than the first voltage. A predetermined voltage obtained by adding the second voltage to a threshold voltage of a transistor in the second/third switch circuit is applied to the gate terminal thereof, and ends of the data lines are connected to the source and drain terminals thereof.
