Abstract
A semiconductor memory device includes a memory cell, and a dynamic latch type sense amplifier including transistors that form not only a dynamic latch circuit which holds or releases data but also charge transfer gates via which charges are applied to or received from bit lines. Data is read from the cell connected to the bit lines at a same time as a precharging operation on the bit lines.
