We propose an asymmetric write algorithm of step-down set/step-up reset without verify for the first time. The demonstration is carried out on a 128Kb test macro of AlOx/WOx bi-layer ReRAM fabricated based on 0.18µm logic process. The set and reset energy per bit are reduced by 34% and 20% respectively. The set and reset access time decrease by 54% and 32% respectively. The mean value of endurance...
We find that the Electrolyte-Oxide-Semiconductor (EOS) structure, which is utilized a lot in micro/nanofluidic devices, is not perfectly insulated as previously believed. There is a significant leakage current through the insulator, and the I–V relationship shows one-way conductivity like a diode. We build a model considering the implantation of ions under forward bias and formation of conductive...
Experiments on Z-pinch has been carried out based on a 2 MA pulsed power facility. Gas puff and wire array liners were tested at current 1.4 ∼ 2.1 MA with rise time 80 ∼ 100 ns. For Krypton specific mass of 23 and 47 µg/cm, soft X-ray yield of 55 and 62 kJ, radiation power of 1.9 and 1.7 TW have been obtained, with imploding time of 90 and 118 ns corresponding to current of 1.4 and 1.5 MA and rise...
