Characterization of Phase change Memory Cell for Contact Area

An ideal semiconductor memory technology would combine or unify the attractive features of these technologies without acquiring any of the unattractive features. Such a memory technology, Phase Change RAM is now being developed using the class of elements known as chalcogenides. It is expected that this technology will eventually allow chips that have SRAM speed, DRAM cost, and Flash power characteristics and non-volatility.
