Abstract
A semiconductor memory device includes a transmission circuit and a control circuit. The transmission circuit is configured to obtain write data and transmit that into a memory cell array according to the external clock signal when the chip selection signal is asserted. The control circuit is configured to control the transmission circuit to transmit first write data into the memory cell array when the chip selection signal changes from assertion to negation during the input period of the first write data, according to the external clock signal.
