A semiconductor device comprises a memory cell block and a sense amplifier zone. A selection gate included in the sense amplifier zone is turned on for selectively coupling the memory cell block with the sense amplifier zone. Local drivers are dispersively arranged on a BLI wire transmitting a gate control signal, and a driver is arranged on an end of the BLI wire. The driver pulls down the potential of the BLI wire at a high speed.
