ABSTRACT:
A semiconductor storage device according to one embodiment of the present invention, comprising: FBCs (Floating Body Cells) which store data by accumulating a majority carrier in a floating channel body; and sense amplifiers which perform control reading out data stored in said FBC, wherein each of said sense amplifier includes: a pair of sense nodes provided corresponding to a bit line pair to which said FBC is connected; a pair of load which flow currents through said pair of sense nodes; latch circuits which latch potentials of said pair of sense nodes when a potential difference between said pair of sense nodes reaches a predetermined value; and an output control circuit which outputs latched outputs of said latch circuits at a predetermined timing and feeds back the latched outputs to said bit line pair side to again write it into said FBC.
