Claim 12:
13. A memory, comprising:
a substrate; and
a storage area comprising a plurality of storage units disposed on the substrate, wherein each of the storage units comprises:
a transistor disposed on the substrate and comprising a drain; and
a magnetic tunnel junction (MTJ) storage element electrically coupled to the transistor, wherein the MTJ storage element comprises:
a bottom electrode electrically coupled to the drain using a conduction structure, wherein the conduction structure comprises a first conduction part, wherein the first conduction part comprises:
a first metal wire; and
a first via hole directly coupled to the first metal wire and the drain and comprising a first connection passage;

a top electrode; and
an MTJ located between the bottom electrode and the top electrode;

a plurality of wiring layers disposed between the transistor and the MTJ storage element, wherein the wiring layers comprise:
a first wiring layer; and
a second wiring layer disposed between the first wiring layer and the transistor; and

a dielectric layer filled between adjacent wiring layers of the wiring layers and between a wiring layer closest to the transistor and the transistor,
wherein the first via hole penetrates the dielectric layer and the second wiring layer,
wherein the first connection passage is isolated from metal wires at the second wiring layer,
wherein the storage area comprises at least two first conduction parts, and
wherein the at least two first conduction parts are disposed along a thickness direction of the substrate, and any adjacent first conduction parts are directly connected.
