Abstract
A semiconductor memory has sense amplifiers coupled to complementary pairs of bit lines. A first switching element couples the sense amplifiers to a first potential, so that the sense amplifiers can bring one bit line in each pair of bit lines from a precharged state to the first potential. A second switching element couples the sense amplifiers to a shunt node. A third switching element couples the shunt node to the first potential. A capacitor capacitively couples the shunt node to a second potential different from the first potential.
