Abstract
A sense amplifier is connected to a pair of folded bit lines via selection gates. At the time of reading data in a memory cell connected to the bit line, the pair of folded bit lines enter a floating state. At this time, the selection gate is turned off to disconnect the bit line from a sense node. After that, a potential is supplied to the bit line from an equalizer. Consequently, a semiconductor memory device of the invention can suppress deterioration in charge holding capability of a memory cell and prevent erroneous operation.
