PURPOSE: A low-power ROM is provided to be capable of reducing an area while lowering power consumption at a read operation. CONSTITUTION: Column selection transistors(Ms1-Msn) select one of a plurality of bit lines. A common connection terminal is connected in common to one ends of the column selection transistors, and precharges the bit lines with a charge sharing voltage when the column selection transistors are turned on. A precharge part(Mp1) precharges the common connection terminal with a power supply voltage(VCC). A reference voltage generating part is connected to the precharge part, and generates a reference voltage used to compare voltages of the bit lines. A sense amplifier(SA) receives the reference voltage and a charge sharing voltage of the common connection terminal.
