Abstract
Provided is a monolithic integration of resistive memory with complementary metal oxide semiconductor using integrated circuit foundry processes. A memory device is provided that includes a substrate comprising one or more complementary metal-oxide semiconductor devices, a first insulator layer formed on the substrate; and a monolithic stack. The monolithic stack includes multiple layers fabricated as part of a monolithic process over the first insulator layer. The multiple layers include a first metal layer, a second insulator layer, and a second metal layer. A resistive memory device structure is formed within the second insulator layer and within a thermal budget of the one or more complementary metal-oxide semiconductor devices. The resistive memory device structure is implemented as a pillar device or as a via device. Further, the first metal layer is coupled to the second metal layer.
