A semiconductor storage device includes: a memory cell array including memory cells, each of the memory cells having a variable resistance element; and a control circuit configured to apply a control voltage, which is necessary for the variable resistance element to transit a resistance state, to a selected memory cell. When applying the control voltage plural times, the control circuit operates to set a value of the control voltage applied in a first control voltage application operation to be substantially equal to a minimum value of distribution of the voltage values of all the memory cells in the memory cell array required to transit the resistance state of the variable resistance element from a high resistance state to a low resistance state. The control circuit operates to perform a plurality of control voltage application operations by increasing the value of the control voltage by a certain value.
