ABSTRACT:
A semiconductor memory has at least a pair of bit lines, a plurality of word lines crossing the pair of bit lines, a pair of dummy word lines crossing the pair of bit lines, memory cells arranged at intersections between the bit lines and the word lines, dummy cells arranged at intersections between any the bit lines and the dummy word lines, a sense amplifier connected to the pair of bit lines, and a means for equalizing the potentials of the pair of bit lines. Each of the memory cell has a transistor and a capacitor. Each dummy cell has the same construction as each memory cell. The pair of bit lines and dummy cell capacitors are electrically connected at a predetermined timing and are set at a third voltage, the corresponding dummy cell is disconnected from one of the bit line pair, to which a selected memory cell capacitor is connected. Subsequently, a voltage difference between voltages on the bit lines is detected.
