Recent Advances on Neuromorphic Systems Using Phase-Change Materials

Realization of brain-like computer has always been human's ultimate dream. Today, the possibility of having this dream come true has been significantly boosted due to the advent of several emerging non-volatile memory devices. Within these innovative technologies, phase-change memory device has been commonly regarded as the most promising candidate to imitate the biological brain, owing to its ...

Advances in Phase Change Memory Technology

Phase Change Memory is one of the best candidates for next generation non-volatile memory which can enlarge its applications segment, due to improved performances, and can fulfil the requirements for future down-scaling. Thermal, electrical and geometrical aspects controlling the functionality of a chalcogenide-based phase change memory cell are analysed. Processing condition effects, material ...

An Algorithm based on Predicting the Interface in Phase Change Materials

Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM)  a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...

Thermal Transport in Phase Change Memory Materials

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...
