Abstract
One of the two data input/output line pairs and the selected bit line pair included in a memory cell array are connected by a column switch, and the read out data is output to a preamplifier through a switching circuit. A data input/output line pair of the data input/output line pairs which is not used for data transmission is equalized by an equalizing circuit. Therefore, data readout and equalizing operation are carried out in parallel, thereby achieving high-speed data readout.
