Strong LCICD (liquid-crystalline induced circular dichroism) was observed when a photochromic dichroic dye, 1, was doped into a cholesteric film of poly[(γ-benzyl L-glutamate)-co-(γ-dodecyl L-glutamate)]. The ICD at the absorption band of anthraqui

Poly(γ-benzyl L-glutamate-co-γ-dodecyl L-glutamate) doped with an azobenzene derivative was studied. Optimum conditions for the induced circular dichroism (ICD) intensity were explored by varying the cholesteric pitch of the film and the content of

We report a novel nonvolatile dual-layered electrolytic resistance memory composed of a conductive Cu ion activated layer and a thin insulator for the first time. An ON/OFF mechanism of this new type memory is postulated as follows: Cu ions pierce th

In this paper, we study to reduce the switching dispersion and improve 0/1 separation of Magnetic Tunnel Junction (MTJ) elements in order to realize high density MRAM. Various kinds of MTJ sizes and shapes have been evaluated and conclude that in ell

A calculation of the intrinsic spin transfer switching current Ic0 is realized in the magnetic tunnel junctions (MTJs). Ic0 is determined by the distribution of Ic in repeated measurements, assuming the linear decrease of the thermal stability by inc

The reliability in magnetoresistive random access memory (MRAM) write operation was investigated for both toggle and asteroid memory chips developed with 0.18μm CMOS process. Thermally activated magnetization reversal, being the dominant origin of t
