Description

The FM25H20 is a 2-megabit nonvolatile memory

employing an advanced ferroelectric process. A

ferroelectric random access memory or F-RAM is

nonvolatile and performs reads and writes like a

RAM. It provides reliable data retention for 10 years

while eliminating the complexities, overhead, and

system level reliability problems caused by Serial

Flash and other nonvolatile memories.

Unlike Serial Flash, the FM25H20 performs write

operations at bus speed. No write delays are incurred.

Data is written to the memory array immediately

after it has been transferred to the device. The next

bus cycle may commence without the need for data

polling. The product offers virtually unlimited write

endurance, orders of magnitude more endurance than

Serial Flash. Also, F-RAM exhibits lower power

consumption than Serial Flash.

These capabilities make the FM25H20 ideal for

nonvolatile memory applications requiring frequent

or rapid writes or low power operation. Examples

range from data collection, where the number of

write cycles may be critical, to demanding industrial

controls where the long write time of Serial Flash can

cause data loss.

The FM25H20 provides substantial benefits to users

of Serial Flash as a hardware drop-in replacement.

The FM25H20 uses the high-speed SPI bus, which

enhances the high-speed write capability of F-RAM

technology. Device specifications are guaranteed

over an industrial temperature range of -40°C to

+85°C.

This is a product in the pre-production phase of development. Device

characterization is complete and Ramtron does not expect to change the

specifications. Ramtron will issue a Product Change Notice if any

specification changes are made.
