A semiconductor storage device includes a memory cell array having memory cells positioned at respective intersections between a plurality of first wirings and a plurality of second wirings, each of the memory cells having a rectifier element and a variable resistance element connected in series, and a control circuit selectively driving the first and second wirings. The control circuit applies a first voltage to the selected first wiring and applies a second voltage to the selected second wiring to apply a certain potential difference to a selected memory cell positioned at a intersection between the selected first and second wirings, and brings at least one of nonselected first wirings into a floating state.
