ABSTRACT:
A dynamic semiconductor memory comprising memory cells each including a pair of complementary bit lines, a storage capacitor and a device for selecting that capacitor. The memory further comprises a sense amplifier and a control device, and a greater differential voltage can be obtained from these bit lines by varying the ratio of their floating capacitance. Thus, the conventional requirement for balancing the complementary bit lines is eliminated and the lines can be formed in a multi-layer structure. This contributes significantly to making the memory cell areas smaller.
