Ferroelectric RAM

Ferroelectric RAM (FeRAM, F-RAM or FRAM) is a random-access memory similar in construction to DRAM but uses 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. FeRAM advantages over flash include: lower power usage, faster write performance and a much greater maximum number of write-erase cycles (exceeding 10 for 3.3 V devices). Disadvantages of FeRAM are much lower storage densities than flash devices, storage capacity limitations, and higher cost.

Famous quotes containing the word ram:

    At one time or another, almost every politician needs an honest man so badly that, like a ravenous wolf, he breaks into a sheep-fold: not to devour the ram he has stolen, however, but rather to conceal himself behind its wooly back.
    Friedrich Nietzsche (1844–1900)
