ABSTRACT:
In a semiconductor memory including first and second bit lines complementary to each other and provided for each one memory cell column, and a sense amplifier connected to the first and second bit lines, for sensing and amplifying a voltage difference between the first and second bit lines, a first pull-up circuit is connected to the first bit line, for pulling up, in accordance with a potential of the second bit line, the first bit line to a high voltage supply potential. A second pull-up circuit is connected to the second bit line, for pulling up, in accordance with a potential of the second bit line, the second bit line to a high level potential lower than that the high voltage supply potential by a predetermined potential difference.
