Ramtron pioneered the integration of ferroelectric materials into semiconductor products that enabled a new class of nonvolatile memory, called ferroelectric random access memory, or F-RAM.
Less commonly, an electric order can exist at the macroscopic scale; such is the case with what are known as ferroelectric compounds.
A saffron-coloured crystal could provide a step towards greener electronics. computer memory store information using metals that are ferroelectric, meaning they form positive and negative poles when placed in an electric field.
Newswise - Scientists at Tohoku University in Japan have recorded data at a density of 4 trillion bits per square inch, which is a world record for the experimental "ferroelectric" data storage method.

The authors believe that using phase transitions such as ferroelectric switching to implement memory and computing is the real fundamental distinction of future information technologies.
Almost exactly two years ago, a team led by Joseph Woicik of NIST and several other federal, academic and industrial laboratories combined precision X-ray spectroscopy data from the NIST beamlines at the National Synchrotron Light Source with theoretical calculations to demonstrate that by carefully layering a thin film of strontium titanate onto a pure silicon crystal, they could distort the titanium compound into something it normally wasn't-a so-called "ferroelectric" compound that might serve as a fast, efficient medium for data storage.
Most have resulted in ferroelectric transistors that have data retention time, also known as operational lifetime for a memory card, of few hours to a few days.
“There could still be trouble with electronic traps at the interface, electrical leakage through the ferroelectric since it is quite thin and manufacturability.”
Schlom says the research team is still a ways off from its goal of creating a complete ferroelectric transistor.
