Abstract: In some embodiments, the present disclosure relates to an integrated circuit. The integrated circuit has a magnetic tunnel junction (MTJ) device disposed within a dielectric structure over a substrate. The MTJ device has a MTJ disposed between a first electrode and a second electrode. A first unipolar selector is disposed within the dielectric structure and is coupled to the first electrode. The first unipolar selector is configured to allow current to flow through the MTJ device along a first direction. A second unipolar selector is disposed within the dielectric structure and is coupled to the first electrode. The second unipolar selector is configured to allow current to flow through the MTJ device along a second direction opposite the first direction.

Abstract: Placement methods described in this disclosure provide placement and routing rules where a system implementing the automatic placement and routing (APR) method arranges standard cell structures in a vertical direction that is perpendicular to the fins but parallel to the cell height. Layout methods described in this disclosure also improve device density and further reduce cell height by incorporating vertical power supply lines into standard cell structures. Pin connections can be used to electrically connect the power supply lines to standard cell structures, thus improving device density and performance. The APR process is also configured to rotate standard cells to optimize device layout.

Abstract: A memory device includes a substrate, an etch stop layer, a protective layer, and a resistance switching element. The substrate has a memory region and a logic region, and includes a metallization pattern therein. The etch stop layer is over the substrate, and has a first portion over the memory region and a second portion over the logic region. The protective layer covers the first portion of the etch stop layer. The protective layer does not cover the second portion of the etch stop layer. The resistance switching element is over the memory region, and the resistance switching element is electrically connected to the metallization pattern through the etch stop layer and the protective layer.
