Resumen:
In this paper, a non-volatile memory cell of Te-based chalcogenide
material is proposed and modeled. It is formed by layers of three
materials: an insulating material, a conductor and a sensitive material:
Te-based chalcogenide material. A 2D model using a finite element
method has been developed for the simulation of the thermal behaviour of
the cell. Temporal evolution of temperature maps is obtained. The model
is applied to alloys of the Ge?Sb?Te system. The computed results allow
us to understand the role played by the variables involved (thickness
of different layers, cell radius, composition of the chalcogenide glass)
in order to optimize the cell structure.
