FRAM the mainstream memory circle

In the mid - 1990 - s people think ferroelectric memory (FRAM, or FeRAM) will become the mainstream technology, but as with most new memory technology, still did not rise as expected.FRAM the inner workings of principle similar to DRAM, and SRAMAs the high speed, and as a non-volatile flash memory;When the first successful FRAM circuit, and its general function was the personage inside course of study thinks can block instead of an SRAM and DRAM and EEPROM in many applications.

 

"That didn't happen," semiconductor industry analyst Jim Handy (from Objective Analysis) in the Cypress FRAM Ramtron pointed out: the supplier "FRAM technology cost is more expensive than producing traditional memory."In the late 80 s, FRAM the developers because they do not understand the physical properties of ferroelectric materials, and encountered many problems.

Although after a difficult time FRAM are already commercialized production at present, different product line is suitable for many applications.Handy in said recently that someone noticed: "FRAM is the mainstream technology of the future, but also doomed to maintain such patterns;FRAM in certain aspects of a certain period of time is to have a certain potential, but haven't really going mainstream."

As with all memory technology, expensive cost is a major obstacle to expand the market;FRAM need a deposition in the standard silicon substrate layer of Perovskite Perovskite crystal, Perovskite crystal containing element interferes with silicon transistors, therefore need a barrier layer isolation Perovskite and at the bottom of the silicon substrate.Hady, said this structure increased the FRAM component manufacturing cost.

Market to the FRAM does have some needs;According to the Research and Markets for about a year ago, according to market Research report forecasts published FRAM Markets around the world from 2013 to 2018 to 16.4% of the compound average annual growth rate (CAGR), the low power consumption characteristics is the key to promote the market growth.

FRAM suppliers include Ramtrom now relegated to Cypress, Texas instruments (TI) and Fujitsu semiconductor (Fujitsu), various companies have expanded in the FRAM hardware and software aspects of r&d investment, thus improve the performance of FRAM and benefit, also extended its application field.
