IC: FM1208S-200CC
Manufacturer: RAMTRON
Description: NVRAM (ferroelectric based)Ferroelectric materials are analogous to ferromagnetic materials, though neither actually need to contain any iron. Ferromagnetic materials, used in core memories, will retain a magnetic field that's been applied to it.
Core memories consist of ferromagnetic rings strung together on tiny wires. The wires will induce magnetic fields in the rings, which can later be read back. Usually reading this memory will erase it, so once a bit is read, it is written back. This type of memory is expensive because it has to be constructed physically, but is very fast and non-volatile. Unfortunately it's also large and heavy, compared to other technologies.
Ferroelectric materials retain an electric field rather than a magnetic field. like core memories, they are fast and non-volatile, but bits have to be rewritten when read. Unlike core memories, ferroelectric memories can be fabricated on silicon chips
