A semiconductor storage device according to an embodiment includes wells in a semiconductor substrate, fins formed on the wells, gate electrodes provided on one side and another opposite side of each fin via a gate insulating film to form a channel region in the fin, impurity-diffused layers that each form a potential barrier that confines holes in a body region within the channel region, and source/drain layers each formed at the fin such that the channel region is sandwiched between the source layer and the drain layer. At the time of writing of data ‘1’, a gate voltage is set to a negative potential, a well bias voltage is set to a positive potential, and a drain voltage is set to a positive potential. |
