Abstract
A storage device includes a first interconnection, a second interconnection, a memory cell connected between the first and second interconnections and including a variable resistance element and a switching element that is connected in series to the variable resistance element, and a control circuit configured to exercise control of a read operation to read data stored in the memory cell. The control circuit exercises control in such a manner as to set the first interconnection which has been charged with a first voltage and the second interconnection which has been charged with a second voltage into floating states, to set the switching element into an on-state by discharging the second interconnection set into the floating state to thereby increase a voltage applied to the memory cell, and to read the data stored in the memory cell in a state in which the switching element is set into the on-state.
