sentences:  The capacitor has two terminals, one of which is connected to its access transistor, and the other to either ground or VCC/2.In modern DRAMs, the latter case is more common, since it allows faster operation.In modern DRAMs, a voltage of +VCC/2 across the capacitor is required to store a logic one; and a voltage of -VCC/2 across the capacitor is required to store a logic zero.
