Abstract
An equalizer control line BLEQ shared by all sense amplifiers SA in each row in each submat SM is connected to a first equalizer control line driver consisting of P-type MOS transistors installed at the left end of the submat SM and is connected to several second equalizer control line drivers 32 consisting of N-type MOS transistors installed by dividing in a cross area 16 of each row through which the equalizer control line BLEQ passes. In order to turn on the equalizers of the bit line pair connected to each sense amplifier S, the first equalizer control line driver is operated to drive the equalizer control line BLEQ to the H level potential. In order to turn off the equalizers of each bit line pair, the second equalizer control line drivers 32 are operated to drive the equalizer control line BLEQ to the L level potential. The first and second equalizer control line drivers are complementarily operated. One of them is driven, and the other is turned off (blocked).
