    • A semiconductor memory device is provided which has a hierarchical bit line structure and can perform a high-speed read operation even with a low voltage. A subarray 12 includes a first MOS transistor PD1 for charging a main bit line MBL1 and a second MOS transistor PS1 for charging a sub-bit line SBL1—1. The source electrode of the second MOS transistor PS1 is connected to a power source voltage, and the source electrode of the first MOS transistor PD1 is connected via a fourth MOS transistor PD2 to the power source voltage. Since there is not a resistance between the main bit line MBL1 and the sub-bit line SBL1—1, which is present if a transistor is used to achieve conduction therebetween, discharging of the main bit line and charging of the sub-bit line can be performed with high speed.
