Key advantage FerroelectricRAM and how it’s differ from RAM

What is Ferroelectric RAM and how it differs from RAM? Who is developing current FeRAM technology? Let me know FeRAM cell and its working mechanism. What is the main scope of its work? Is FeRAM similar to DRAM? What are advantages to use Ferroelectric RAM? Is FeRAM faster than DRAM? Is FeRAM required less charge than DRAM? In which sector has FeRAM product used? What is CMOS? How does it work? Has FeRAM any limitation? Thank You
