RESISTANCE-CHANGE MEMORY
First Claim
1. A resistance-change memory comprising:
- a first bit line and a second bit line extending in the same direction;
a third bit line extending parallel to the first bit line and the second bit line;
a fourth bit line and a fifth bit line extending in the same direction;
a sixth bit line extending parallel to the fourth bit line and the fifth bit line;
a first memory element which comprises a first terminal connected to the first bit line and a second terminal connected to the third bit line, and is configured to change to either a first resistance state or a second resistance state;
a first reference element comprising a first terminal connected to the fourth bit line and a second terminal connected to the sixth bit line, the first reference element being set in the first resistance state;
a second reference element making a pair with the first reference element, comprising a first terminal connected to the fifth bit line and a second terminal connected to the sixth bit line, the second reference element being set in the second resistance state; and
a sense amplifier comprising a first input terminal connected to the first bit line and a second input terminal connected to the fourth bit line.

Abstract
A resistance-change memory includes first and second bit lines running in the same direction, a third bit line running parallel to the first and second bit lines, fourth and fifth bit lines running in the same direction, a sixth bit line running parallel to the fourth and fifth bit lines, a first memory element which has one and the other terminals connected to the first and third bit lines, and changes to one of first and second resistance states, a first reference element having one and the other terminals connected to the fourth and sixth bit lines, and set in the first resistance state, a second reference element having one and the other terminals connected to the fifth and sixth bit lines, and set in the second resistance state, and a sense amplifier having first and second input terminals connected to the first and fourth bit lines.
