Radiation-Resistant Memory Device Based on Chalcogenide Glassy Semiconductor

Some Peculiarities of Photo-structural Transformations in Amorphous Chalcogenide Glassy Semiconductor Films

587 Abstract— The absence of deep traps for electrons in the spectrum of As 40 Se 30 S 30 localized states films obtained by ion sputtering was determined. Bipolar drift of charge carriers was found in amorphous As 40 Se 30 S 30 films of chalcogenide glassy semiconductors, obtained by ion-plasma sputtering of high-frequency, unlike the films of these materials obtained by thermal evaporation.

Forced Ion Migration for Chalcogenide Phase Change Memory Device

Chalcogenide-Based Non-Volatile Memory Technology

– Chalcogenide is a proven phase change material used in re-writeable CDs and DVDs. This material changes phases, reversibly and quickly, between an amorphous state that is dull in appearance and electrically high in resistance, and a polycrystalline state that is highly reflective and low in resistance. The application of this commercially proven technology to create dense, high-speed, non-vol...

Atomistic Simulations of Flash Memory Materials Based on Chalcogenide Glasses

In the last decade, the market for non-volatile computer storage has experienced rapid growth. However, as the device size scales down, currently used NOR and NAND technology is facing limitations from tunnel oxide and electrostatic interactions between cells (Lacaita & Wouters, 2008). To solve the scaling problems, in the last fifteen years, a number of alternative Flash memory technologies ha...

A chalcogenide-based device with potential for multi-state storage

We have investigated electrical properties of a chalcogenide-based device with naturally oxidized Al electrodes. Intermediate-resistance (IR) states exhibited by current–voltage (I–V) characteristics, dynamic resistance change as a function of pulse height and decay behavior from a low-resistance state of such a device make multi-state storage feasible. These IR states could be induced by elect...
