Abstract
After a controlled strong lowering of the word line potential for the purpose of addressing a cell, said potential is immediately recharged simultaneously increasing the potential on the N side of the two PNP injectors of the cell and causing the injector capacitances of the selected storage cells and the bit line capacitances to form a capacitive voltage divider, so that the bit lines connected thereto are recharged to different degrees by the different magnitudes of the injector capacitances. Thus, the differential signal formed on the bit lines is noticeably amplified by the supply of currents of different magnitudes.
