Abstract
A semiconductor memory device 251 has a sense amplifier 7 of shared sense amplifier type. A switching signal generating circuit 253 is provided for application of control signals .phi..sub.1 and .phi..sub.2 to a control electrode of a connection transistor of sense amplifier 7. Switching signal generating circuit 253 applies control signals .phi..sub.1 and .phi..sub.2 which is boosted only for a prescribed time period after the rise of external /RAS signal to the control electrode of the connection transistor of sense amplifier 7. Therefore, as compared with the operation in which control signals .phi..sub.1 and .phi..sub.2 which are constantly boosted are applied, power consumption can be reduced.
