FeRAM

   Also found in: Acronyms 0.06 sec.

(FerroelectricRAM) A non-volatile, random access memory technology that uses a ferroelectric capacitor to store a binary state (0 or 1) as two voltages. It uses one or two transistors to read and write the capacitor. FeRAM was designed to replace flash memory because it writes considerably faster, uses less power and is byte addressable. It has virtually unlimited write cycles, making it superior to flash in applications that require constant updating. FeRAM can also be more easily integrated with other circuits on a semiconductor chip. In addition, FeRAM can be used to replace SRAM chips.

Ramtron International, Colorado Springs, CO (www.ramtron.com) was the first to produce a commercial FeRAM chip in 1992. Ramtron's Ferroelectric RAM (FRAM) technology is also licensed to other companies. See ferroelectric capacitor.

In another approach, called ferroelectric RAM, abbreviated as FRAM or FeRAM, materials store electric fields in orientations that can represent digital bits.
Quanquam quid vel hoc opus erat dicere, quasi non ipso ex vultu fronteque, quod aiunt, satis quae sim prae me feram, aut quasi si quis me Mineruam aut Sophiam esse contendat, non statim solo possit obtutu coargui, etiam si nulla accedat oratio, minime mendax animi speculum" (74, 65-68).
The company has made recent inventions in FeRAM and has developed a silicon- based design of its HCS MRAM.
