Patent ID: 7851777

Claim:
A memory comprising at least five memory cells including a resistance-changing function body, a select transistor for selecting the resistance-changing function body and a rectifying function body for determining a direction of a current that flows through the resistance-changing function body, the resistance-changing function body comprising: an object made of a first substance and interposed between a first electrode and a second electrode; and a plurality of particles made of a second substance and arranged within the object so that an electrical resistance between the first electrode and the second electrode is changed before and after application of a specified voltage to between the first electrode and the second electrode, wherein the first substance makes an electrical barrier against the second substance, each of the memory cells is connected between a bit line and a source line extended in a direction of column, and the select transistor of each of the memory cells is controlled by a word line extended in a direction of row, second and fourth cells are arranged mutually adjacently in the direction of row, and third and fifth cells are arranged mutually adjacently in the direction of column, with respect to a first cell of the five memory cells, the first cell and the second cell have a shared bit line, a shared word line and unshared source lines, the first cell and the third cell have a shared bit line, a shared source line and unshared word lines, the first cell and the fourth cell have a shared source line, a shared word line and unshared bit lines, and the first cell and the fifth cell have a shared word line, a source line of the first cell and a bit line of the fifth cell are shared, and a bit line of the first cell and a source line of the fifth cell are shared.
