Semiconductor device comprising precharge circuit for precharging and/or equalizing global input and output line and layout of precharging and/or equalizing transistor

摘要

The global input and output line pre-charge and / or a semiconductor device having a pre-charge and pre-circuit for equalizing The layout of the charge and / or the equalizing transistor is disclosed. The semiconductor device according to the invention comprises a pair of local input and output lines connected to the pair of bit lines through a first switching circuit; A pair of global input and output lines connected to the pair of local input and output lines via a second switching circuit; Output line sense amplifiers connected to the pair of global input and output lines will be detected and amplified by the output data of the pair of global input and output lines; And, it disposed between said second switching circuit and the input-output line sense amplifiers, a plurality of the precharging is connected to the pair of global input and output lines of the pair of global input and output lines in response to a first pre-charge control signal 1 is characterized in that it comprises a pre-charge circuit. In accordance with the present invention, there is an effect global IO line pair is precharged in a short time.
