ABSTRACT:
A static type semiconductor memory device has a power down mode in which an operating voltage for peripheral circuits, such as decoder circuits, is turned off when the memory chip is in a non-selected condition. 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.
