One embodiment includes a plurality of word lines, a plurality of bit lines intersecting with the plurality of word lines, a plurality of memory cells formed at intersections of and connected to the plurality of word lines and the plurality of bit lines. Each of the plurality of memory cells may be a floating body cell. A bit line selecting circuit may be configured to selectively connect each of the plurality of bit lines to an output bit line. The embodiment may further include plurality of sense amplifiers, where the plurality of sense amplifiers is greater than one and less than the plurality of bit lines in number. A sense amplifier switching structure may be configured to selectively connect each of the plurality of sense amplifiers to the output bit line.
