Abstract(in Japanese) (See Japanese page)
Abstract(in English) High-speed, high-density, low-cost, and nonvolatile memories are required in computer and multimedia systems. Phase change random access memory (PRAM) material generally consists of a chalcogenide semiconductor thin film. Some chalcogenide semiconductor has two stable states, which are the low conductive amorphous state and the high conductive crystalline state, and the one state can be converted to the other state by applying electric pulses. Reversible phase change between amorphous and crystalline states is exploited to store bits of information. In this work, various characteristics of PRAM using telluride chalcogenide glasses were reported.
