Popis: International audience; In this work, we demonstrate the integration feasibility of Crossbar arrays based on Ovonic-Threshold Switching (OTS) selector and "Wall"-based Phase-Change Memory, realized with a "Double-Patterned Self-Aligned" (DPSA) structure in the Back-End-of-Line (BEOL) of the CMOS fabrication. We fabricated devices with critical dimensions down to 60 nm×80 nm, integrating materials providing improved thermal stability (against BEOL thermal budget). Preliminary statistical electrical tests performed in 1 kb 1T1S1R arrays confirm the devices correct programming and cycling operations. These results pave the way to the integration of Crossbar arrays in embedded applications.
