This invention addresses the complexity and cost issues in existing RRAM technologies by introducing a selector-less RRAM with integrated non-linearity within a single memory layer. The innovative design achieves high non-linearity (100-10000x) and a sharp slope (10-100mV/dec) in the low resistance state (LRS) without the need for additional non-linear devices or layers. Utilizing a perovskite oxide layer (ABO3-d) and combining noble and reactive metals, this solution simplifies fabrication, reduces operating voltages and costs, and enhances device performance. Relevant to semiconductor manufacturing, memory device production, and electronics, this technology offers advantages in non-volatile memory applications and high-density storage, contributing to more efficient and cost-effective memory devices.
