Design to a higher standard

Ferroelectric random access memory (F-RAM) products combine

the nonvolatile data storage capability of ROM with the beneﬁts

of RAM.

Ramtron’s broad line of specialized semiconductor memory,

microcontroller and integrated semiconductor solutions are found in a

wide range of industries and applications including metering, computing,

automotive, and consumer.

Ramtron products are also found in industrial, scientiﬁc, and medical applications

that thrive on the high-speed, high-endurance, and low power consumption of F-RAM.

Beneﬁts of nonvolatile RAM

F-RAM performs read and write operations at the

same speed. Because F-RAM writes data at bus speed,

there are no delays before the written data becomes

nonvolatile. Floating gate memories have a long write

delay of ﬁve milliseconds. F-RAM writes in nanoseconds,

essential in applications like auto safety systems.

with no strings attached.

F-RAM offers virtually unlimited write endurance, which

means it doesn’t wear out like other nonvolatile memory

devices. Floating gate devices experience a hard failure

and stop writing in as little as 10⁵cycles, making them

unsuitable for write-intensive applications.

High

Endurance

datasheets, white papers, and more.

F-RAM operates without a charge pump, enabling low

power consumption. Floating gate devices demand high

voltage during write operations. F-RAM writes at the

native voltage of the manufacturing process: 5V, 3V, or

even less on more advanced processes.

A primer on F-RAM memory

F-RAM offers a unique set of features relative to other

semiconductor technologies. Established semiconductor

memories can be divided into two categories: volatile and

nonvolatile. Volatile memory includes SRAM (static random

access memory) and DRAM (dynamic random access memory),

among others. RAM type devices are easy to use, offer high

performance, but they share a common vulnerability: stored

memory is lost when the power supply is removed.

The F-RAM chip contains a thin ferroelectric ﬁlm of lead

zirconate titanate [Pb(Zr,Ti)O₃], commonly referred to as PZT

(Figure 1). The Zr/Ti atoms in the PZT change polarity in

an electric ﬁeld, thereby producing a binary switch. Unlike

conventional RAM devices, F-RAM retains its data memory when

power is interrupted. This unique property makes F-RAM a low

power, nonvolatile memory.

Like F-RAM, ROM (read only memory) is a nonvolatile memory

that does not lose its data content when power is removed.

Newer generation ROM, like EEPROM (electrically erasable

programmable read only memory) and ﬂash memory,

can be erased and re-programmed multiple times, but

they require high voltage and write very slowly. ROM-

based technologies eventually wear out (in as little as

10⁵cycles), making them unsuitable for high-endurance

industrial applications.

F-RAM has 10,000 times greater endurance and uses

3,000 times less energy than a typical serial EEPROM

device, and nearly 500 times the write speed.

F-RAM combines the best of RAM and ROM into a

single package that outperforms other nonvolatile memories

with remarkably fast writes, high endurance, and ultra-low

power consumption.

Serial F-RAM Memory

F-RAM serial memories provide reliable data collection, perform reads and writes like

a RAM, and eliminate the complexities, overhead, and system reliability problems of

EEPROM. The I²C serial interface is common and many MCUs implement a dedicated

I²C port. The serial peripheral interface (SPI) is capable of clock rates up to 40MHz.

Batteries bogging you down?

Get hassle-free performance with F-RAM.

New!

Battery backed static random access memory (BBSRAM) are workhorse chips in many data logging

applications, but they have a profound drawback: the battery. Ramtron’s V-Family parallel memory

offer a number of advantages to system designers by removing the system design complexities,

reliability concerns, and functional disadvantages of BBSRAMs.

F-RAM performs like a RAM, but requires no batteries due to their native nonvolatility. F-RAM saves

not only space in the system’s design, but eliminates the need for costly ﬁeld battery replacement,

and risk of exploding or releasing harmful chemicals in harsh operating conditions.

Consider the many functional and design advantages that V-Family F-RAM

bytewide memories offer:

tꢀGreen. No battery reduces environmental impact.

tꢀLꢀ CA and ISO friendly. Supports EPA Life Cycle Assessment and ISO standards helping

to strengthen supplier-customer relationship.

tꢀRꢀ ugged. Industry-standard, reliable solution that’s highly resistant to moisture, shock,

and vibration.

No batteries required.

tꢀLꢀ ess cost. Promotes a lower overall solution cost when considering BBSRAM device cost, board

size, manufacturing complexity, inventory, and long-term maintenance.

tꢀPeace-of-mind. Secure, tamper resistant solution.

Eliminate headaches over

BBSRAM design complexities,

manufacturing heat proﬁles,

and ﬁeld reliability with

Ramtron’s V-Family of F-RAM

bytewide memory.

Ramtron V-Family bytewide memories are drop-in replacements for BBSRAMs. Contact one of our

sales representatives or ﬁeld application engineers today and see how V-Family parallel F-RAM can

improve the performance and reduce the cost of your next design.

Dual and Quad Nonvolatile State Saver

The Ramtron low-power nonvolatile state saver is a logic building block that provides

continuous access to nonvolatile system settings without reading a memory. It enables

storage of signals that may change frequently and without notice, and it allows the

nonvolatile storage of system settings without the system overhead of a serial memory.

These Ramtron F-RAM-based devices save the state of signals on demand and automatically

restore signals to their correct state upon power up.

Ramtron International Corporation is a fabless semiconductor company that

designs, develops, and markets specialized semiconductor memory and integrated

semiconductor solutions for a broad range of applications across targeted vertical

markets. Founded in 1984, Ramtron pioneered the integration of ferroelectric materials into

semiconductor products, which enabled the development of a new class of nonvolatile, high-

performance memory known as ferroelectric random access memory or F-RAM.

Since its inception, Ramtron has supplied over 300-million F-RAM products worldwide,

fueling the company’s product revenue growth. Ramtron is a public company

traded on the Nasdaq Global Market under the symbol RMTR.
