Memristor is short for memory resistor, which provides a functional relation between flux and charge. Professor Leon Chua named and formulated it in his paper\ud "Memristor—The Missing Circuit Element" in 1971. The memristor has a special effect, ‘the delayed switching effect’, which is the memristor switching takes place with a time delay. Content addressable memory (CAM) is a type of associative memories that is adopted in high speed searching applications. The new Memristor-CAM cell has been proposed, which included two memristors; one is used as an important part of the comparator that is instead of the traditional logic gate; and another one is for storing the data as a storage element. In this paper, we report that applying the memristor delayed switching effect to the novel design of the Memristor Content Addressable Memory (M-CAM) cell. The delayed switching effect is used to control the changing time of the memristor’s state, which can enhance the performance, decrease the searching time and save energy.

The first six Chebyshev polynomial coefficients (i.e.,A 08 ,A 01 ,A 10 ,A 11 ,A 02 , A20) were derived from monthly mean geopotential height over East Asia for the period 1951–1983. Spectral analysis of these coefficients reveals relative maxima of power in the frequency bands of 200 months (≈ 16.7 years), 25 months (the quasi-biennial oscillation), 5–6 months, and 2–3 months. Cross-spectral characteristics between Chebyshev coefficients and the Southern Oscillation Index (SOI) were also explored. Coherence spectrum for the zonal and meridional circulation index (A 01 andA 10 ) with the SOI was significant near 4 years, the QBO, and 2–3 months. Some physical explanations were offered for the spatial linkages (i.e., teleconnections) between the SO and atmospheric circulation anomalies over East Asia.
