Abstract
A dynamic random access memory device has a plurality of one-transistor one-capacitor type memory cells each coupled between a first bit line and a second bit line paired with the first bit line, and parasitic capacitance coupled with the first bit line is approximately equal to a parasitic capacitance coupled with the second bit line so that a large potential difference takes place between the first and second bit lines when the storage capacitor is coupled with the first and second bit lines precharged to an intermediate voltage level.
