Fujitsu's Ferroelectric RAM hits 2 MBit

Fujitsu today announced the availability of its 2 Mbit Ferroelectric RAM (FRAM or FeRAM) memory chips, which the company claims is the largest capacity FRAM in volume production in the world. The memory product have the same electrical characteristics and use the same TSOP-48 package as Fujitsu's 1 Mbit FRAM products, equating to double the capacity over previous chips. Sampling price of the chips is set at 2,000 Yen ($16.91 USD).

FRAM is a non-volatile memory that uses a ferroelectric film as the capacitor for data retention and betters flash-based RAM with faster data writing, lower power consumption and higher number of write cycles.

Fujitsu says that FRAM could be used in office equipment to store event counts, or store various parameters and log at every event, without concern for the number of write cycles.  FRAM allows 10 billion read/write cycles, which corresponds to writing 30 times a second continuously for 10 years. Also, FRAM can store data for more than 10 years without a battery.

Other ideal uses of FRAM could be in car navigation systems, multi-function printers, measuring instruments – anywhere non-volatile memory is being used to store various parameters, record operating conditions of equipment or security information.

$67640 per GB or $8455 per Gb? Seems a little pricey to be practical for any type of PC storage. Heck, at $67.64 per MB, it doesn't even seem practical for CE devices. What type of high end equipment would be taking advantage of this stuff?

Those are the prices for sampling a single one. I'm sure economies of scale will take place once production is ramped up.

Until mass market, prices will always be expensive. A lot of this requires more adoption for the price to come down.

This isn't meant for PC or CE storage, it's meant to be used as non-volatile memory in embedded systems for things like sensor readings or logging usage. The lower power consumption is good for remote telemetry units that might be placed in the field and powered off solar. Completely different applications with different requirements.

Well not yet
but FRAM have potential to replace Flash in consumer market. Just need some time to drive cost down.

I think they're pretty clear that this isn't for large storage capacities at this point. It is a newer technology at this point in time, like current flash memory was many years ago. This is for small amounts of data that needs to be accessed alot. They provide some examples in the article you know. Give it 10 years and maybe we'll be talking about it's price per gigabyte then, or maybe we'll be talking about something else per gigabyte.
