Abstract
A semiconductor dynamic read/write memory circuit using one-transistor storage cells and balanced bit lines with differential sense amplifiers employs dummy capacitors which are the same size as the storage capacitors. The dummy cell produces a signal on the bit line half that of the storage cell due to a level-shift circuitry connected to the dummy cells. The dummy capacitor is precharged to a reference voltage, and at the beginning of an active cycle the dummy capacitor is charge-shared with another capacitance of the same size, to change the reference level. The net signal is thus equal to that of a capacitor one-half the size of the storage capacitors.
