Abstract
A plurality sets of bit line pairs are connected to one set of common data line pair respectively through bit line selecting transistors. The common data line pair is coupled to the supply potential through precharging transistors. In the precharging period, a set of bit line pair is selected by a Y decoder to be connected to the common data line pair. On this occasion, the precharging transistor turns on in response to a precharge signal and the selected bit line pair is precharged through the common data line pair. The bit line pair which is not selected is not precharged.
