The static type semiconductor memory device comprises first transistors, which are connected to a pair of data buses and which pull down the potentials of the pair of data buses to a medium potential when the memory chip has changed from a selected condition, to the non-selected condition and second transistors which are connected to the pair of data buses and which pull up the potentials of the pair of data buses to a high potential when the memory chip has changed from a non-selected condition to a selected condition. | |
