Abstract
Disclosed is the addition of a capacitor circuit for augumenting the voltages at predetermined points in a sense amplifying circuit, in order to ensure a satisfactory refreshing of memory cells, since, if the potentials at the connecting points between a sense amplifying circuit and bit lines fall below a predetermined value when the sense amplifying circuit is caused to operate, it is difficult to achieve a complete refreshing of the memory cells.
