Abstract
The data transmission circuit includes: a plurality of local bit line pairs through which data is read simultaneously; a plurality of voltage change detection circuits provided for the plurality of local bit line pairs; a global bit line pair; a plurality of column selection circuits configured to select one of the local bit line pairs and connect the selected local bit line pair to the global bit line pair; and a sense amplifier connected to the global bit line pair. The sense amplifier is controlled by a sense amplifier activation signal to which the outputs of the plurality of voltage change detection circuits are connected, whereby the voltage of a selected read data line pair is amplified using discharge of a non-selected read data line pair, to achieve high-speed read.
