Abstract
An intermediate voltage generator incorporated in a dynamic random memory device is shared between digit lines and counter electrodes of storage capacitors forming parts of memory cells, and supplies an intermediate voltage through precharging transistors to digit lines already shifted to high low voltage levels and directly to the counter electrodes, wherein a switching transistor cuts off the voltage propagation path between the intermediate voltage generator and the precharging transistors in the precharging stage so that the storage capacitors are free from voltage fluctuation due to the precharging operation on the digit lines.
