  • Abstract
    In this letter, a resistive random access memory based on Ni electrode/HfOx, dielectric/n+ Si substrate structure is demonstrated, which can be integrated with Si diode as selector for application in crossbar architecture. The unipolar device shows well-behaved memory performance, such as high ON/OFF resistance ratio (>; 103), good retention characteristics (>; 105 s at 150 °C), satisfactory pulse switching endurance (>; 105 cycles), and a fast programming speed of about 50 ns. More importantly, it also exhibits almost 100% device yield on a 6-in wafer.
