Nov 20, 2020 (The Expresswire) -- "Final Report will add the analysis of the impact of COVID-19 on this industry." Ferroelectric RAM (FeRAM or FRAM [FeRAM is the accepted generic acronym for ferroelectric random-access memory.] Advantages and Disadvantages: Very similar to the MRAM, FeRAM combines the advantages of SRAM -- writing is roughly as fast as reading, and EPROM -- non-volatility and in-circuit programmability. The idea was first proposed in 1952, but it took many years before the idea started to be developed properly as the technologies required to implement it did not exist. FRAM has been described several ways, but most simply put it is a non-volatile memory component that offers very high speed writing, low power consumption, and longer rewrite endurance. Relays     high NRE cost) only applicable to a small niche This requires fewer stages than the number required for incorporating Flash memory onto MCU chips, thereby providing some significant cost reductions. Figure 2 shows the advantages and disadvantages for all of those baseline and prototype memory However around 1999 the first devices were produced and since then companies including Ramtron, Fujitsu, Texas Instruments, Samsung, Matsushita, Infineon and other have been using the technology. FRAM, ferroelectric RAM, is a form of random access memory that combines the fast read and write access of dynamic RAM, DRAM whilst also providing non-volatile capability. As developers often tend to rely on trusted technologies that are guaranteed to deliver the performance they require, they are often reluctant to use technologies like FRAM that are not guaranteed to deliver. Like DRAM, FeRAM’s read process is destructive, necessitating a write-after-read architecture.  FRAM allows systems to retain … One of the first commercial applications of FeRam was curiously enough in Playstation 2.
