Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but using a ferroelectric layer instead of a dielectric layer to achieve non-volatility. FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory .
To date, the only such system to enter widespread production is ferroelectric RAM, or F-RAM (sometimes referred to as FeRAM). F-RAM is a random-access memory similar in construction to DRAM but (instead of a dielectric layer like in DRAM) contains a thin ferroelectric film of lead zirconate titanate [Pb(Zr,Ti)O 3], commonly referred to as PZT ...
Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a form of random-access memory similar in construction to DRAM, both use a capacitor and transistor but instead of using a simple dielectric layer the capacitor, an F-RAM cell contains a thin ferroelectric film of lead zirconate titanate [Pb(Zr,Ti)O 3], commonly referred to as PZT. The Zr/Ti atoms in ...
Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
A ferroelectric field-effect transistor (Fe FET) is a type of field-effect transistor that includes a ferroelectric material sandwiched between the gate electrode and source-drain conduction region of the device (the channel).
February — Tohoku University and Hitachi developed a prototype 2-Mbit non-volatile RAM chip employing spin-transfer torque switching. [ 36 ] August — "IBM, TDK Partner In Magnetic Memory Research on Spin Transfer Torque Switching" IBM and TDK to lower the cost and boost performance of MRAM to hopefully release a product to market.

An alternative memory ready for use is ferroelectric RAM (FRAM or FeRAM). FeRAM adds a small amount of a ferro-electric material to a DRAM cell. The state of the field in the material encodes the bit in a non-destructive format. FeRAM has advantages of NRAM, although the smallest possible cell size is much larger than for NRAM.
