Material Systems For Resistive Memory Cells
A large number of inorganic and organic material systems showing thermal or ionic resistive switching effects have been demonstrated in the literature. These can be grouped into the following categories:
1. phase change chalcogenides like Ge2Sb2Te5 or AgInSbTe
2. binary transition metal oxides like NiO or TiO2
3. perovskites like Sr(Zr)TiO3 or PCMO
4. solid-state electrolytes like GeS, GeSe, SiOx or Cu2S
5. organic charge transfer complexes like CuTCNQ
6. organic donor–acceptor systems like Al AIDCN
7. various molecular systems

Famous quotes containing the words material, systems, memory and/or cells:
“It may be possible to do without dancing entirely. Instances have been known of young people passing many, many months successively, without being at any ball of any description, and no material injury accrue either to body or mind; Mbut when a beginning is made—when felicities of rapid motion have once been, though slightly, felt—it must be a very heavy set that does not ask for more.”
—Jane Austen (1775–1817)
“No civilization ... would ever have been possible without a framework of stability, to provide the wherein for the flux of change. Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
—Hannah Arendt (1906–1975)
“Remember thee?
Ay, thou poor ghost, whiles memory holds a seat
In this distracted globe. Remember thee?
Yea, from the table of my memory
I’ll wipe away all trivial fond records,
All saws of books, all forms, all pressures past
That youth and observation copied there,
And thy commandment all alone shall live
Within the book and volume of my brain,”
—William Shakespeare (1564–1616)
“Madness is locked beneath. It goes into tissues, is swallowed by the cells. The cells go mad. Cancer is their flag. Cancer is the growth of madness denied.”
—Norman Mailer (b. 1923)
