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 second dummy capacitor for each dummy cell. One dummy capacitor is precharged to a reference voltage, and the other is predischarged to ground. The net signal is thus equal to that of a capacitor one-half the size of the storage capacitors.
