Abstract
A semiconductor device includes memory cells of one-transistor one-capacitor connected to n+1 bit lines that are simultaneously driven, sense amplifiers connected to the n+1 bit lines, and a reference voltage generating circuit generates an average voltage of a highest voltage and a lowest voltage among bit line voltages that are obtained by accessing the n+1 bit lines in parallel, and supplying the average voltage to the sense amplifiers as a reference voltage.
