1952: FeRAM - Computer Memory

FeRAM, or Ferroelectric RAM, still feels somewhat exotic today, but its history dates back to 1952, when MIT graduate student Dudley Allen Buck described the principle of FeRAM in his master's thesis entitled Ferroelectrics for Digital Information Storage and Switching. It took more than 30 years for the idea to be picked up again. The technology idea was completed in 1991 at NASA's Jet Propulsion Laboratory. The FeRAM in production today is largely based on technology developed by IP (intellectual property) company Ramtron, while Fujitsu, IBM and Texas Instruments are the most significant producers of FeRAMs at this time.
