Abstract
A semiconductor memory device includes a first bit line connected to a memory cell via a transistor, a transfer gate, a second bit line connected to the first bit line via the transfer gate, a sense amplifier connected to the second bit line, a first precharge circuit for precharging the first bit line, a second precharge circuit for precharging the second bit line, a control circuit which precharges the first bit line by the first precharge circuit after closing the transfer gate, followed by subsequent precharging of the second bit line by the second precharge circuit.
