Abstract:

Since the first realization of capacitor in 1745 followed by conceptualization of resistor and inductor in 1827 and 1831 respectively, the design community has been limited to these three fundamental passive circuit elements. Memristor and memristive constructs at nanoscale have emerged over the last few years through a combination Metal-Insulator-Metal (MIM) processing technology; thus paving the way for an efficient adoption of memristor constructs such as ReRAM crossbar-based architectures. However, a noticeable drawback of the crossbar architecture that remembers to be solved is the existence of sneak- paths between adjacent cells. This work presents a novel approach in implementation of complementary resistive switch based on transparent memristors. The upper TiO 2-x layer was deposited by atomic layer deposition using titanium tetra-isopropoxide and O 2 as the precursor and the oxygen source respectively; with oxygen deficiency of 5%. The lower TiO 2 is 4 nm thick while the upper TiO 2-x layer is 12 nm thick. The fabricated MIM structure has shown promising results in terms of functional reproducibility and high speed switching for digital and low-voltage analog application
