Storage device

A storage device, comprising:

• plural word lines;
• plural data lines that cross the plural word lines;
• plural control lines that cross the plural word lines and are provided so that each is paired with a corresponding one of the plural data lines;
• plural memory cells arranged at each intersection of the plural word lines and the plural data lines and including a storage element the resistance of which varies according to stored information and a first transistor;
• a precharge circuit for precharging the plural data lines and the plural control lines at first potential;
• a common data line;
• a first switching circuit for selecting one of the plural data lines and connecting it to the common data line;
• and
• a second switching circuit for selecting one of the plural control lines corresponding to a selected data line out of the plural data lines and driving it at second potential, such that one of the plural memory cells that exists at an intersection of a selected word line out of the plural word lines, a selected data line out of the plural data lines and a selected control line out of the plural control lines is selected thereby, wherein
• the storage element included in each of the plural memory cells is coupled between a corresponding one of the plural data lines and a corresponding one of the plural control lines.
