    • PROBLEM TO BE SOLVED: To provide a semiconductor storage device for surely executing a set operation, a reset operation and a read operation with respect to a plurality of memory cells. SOLUTION: The semiconductor storage device includes: a memory cell array MA in which the memory cells MC configured of a series connection of diodes Di and variable resistors VR are arranged at crossing parts of a plurality of bit lines BL and a plurality of word lines WL; and a control circuit for alternatively driving the bit line BL and the word line WL. When a predetermined potential difference is applied to a selected memory cell MC arranged at the crossing parts of the bit line BL and the word line WL by the control circuit, the plurality of bit lines BL0 and BL8 to be alternatively driven at the same time by specifying by one address signal CA7 among a plurality of address signals CA0 to CA7 are dispersedly arranged within the memory cell array MA.
