Dynamic semiconductor memory device with decreased clocks

摘要

Disclosed is a dynamic semiconductor memory device with decreased clocks having a pull up circuit associated with a pair of bit lines. The pull up circuit comprises a pair of first switching transistors connected between a power supply line and the associated bit line, and, a pair of second switching transistors. Each gate of the second switching transistors is connected to the bit line of opposite side. The turning on or off of the second switching transistor controls the gate potential of the first switching transistor.
