Abstract

PURPOSE:To sufficiently ensure a write of 0V into a memory cell to increase the working margin of a dynamic RAM, by using the memory cell recharge pulse of the dynamic RAM for the discharge of a differential amplifier. CONSTITUTION:A transistor TR is shifted to a state of conduction by a clock phi to discharge the potential of the source phi3. On the other hand, a TR12 is shifted to a state of conduction by a control signal phi0' to discharge the potential of the source phi3. In this case, the potential of phi3 may possibly float up with a rise of the recharge pulse. To prevent this phenomenon, a TR13 is shifted to a state of conduction by a pulse phi4 to discharge the potential of phi3. As a result, the potential of phi3 never floats up but keeps 0V. Thus 0V can be written enough into a memory cell.
