摘要
A semiconductor memory device comprising memory cells arranged in a matrix with plural pairs of bit lines to be column addressed and connected to sense amplifiers, and word lines to be row addressed and divided into divisional word lines. Output signals of sense amplifiers selected by the column addressing are transferred to respective data lines. The divisional word lines are time-sequentially activated corresponding to the row addressing with the activated states of any two sequential divisional word lines overlapped for a fractional time of the full activation time. The sense amplifiers are grouped into plural groups with respective common column addresses. Each group of sense amplifiers have their outputs to be applied to respective data lines connected to a serial/parallel converter.
