Product Overview
The industry's largest FRAM (Ferroelectric Random Access Memory) supplier, Fujitsu was the first company in the industry to embed FRAM into CMOS logic in 1998 and to release production quantities in 1999. This new generation of non-volatile memory outperforms existing memories like E2PROM and Flash, consumes less power and offers higher speed and endurance to multiple read-and-write operations. FRAM is non-volatile, but operates in other respects like RAM. This breakthrough storage medium is used in a variety of applications including smart cards, RFID, security and many other applications that require high-performance, non-volatile memory.
Fujitsu is the first semiconductor manufacturer to establish an embedded FRAM process. Fujitsu's FRAM devices are produced at its Mie, Japan plant, which is ISO9002 and ISO14001 certified.
Fujitsu provides standalone FRAMs and FRAM for RFIDs as well as COT, foundry and custom design services.
FRAM Material 
PZT (Pb {ZrTi}O3), perovskite-type structure (ABO3) is commonly used as a ferroelectric material. An electric polarization of PZT (shift up/down of Zr/Ti atom) remains after applying and removing an external electric field, from which a non-volatile property results. As a result, the power consumption required for data storage is very low.
Advantages of FRAM
The benefits of FRAM include:
- FRAM is 30,000 times faster than E2PROM
- FRAM provides 1 million times higher endurance over E2PROM
- FRAM offers 200 times lower power consumption than E2PROM
- FRAM integrates excellent tamper-prevention techniques
Product Lineup
Fujitsu provides standalone FRAMs and FRAM for RFIDs as well as COT, foundry and custom design services.
Standalone FRAM
Standalone FRAM can be integrated into any system that requires high-speed, non-volatile memory. FRAM does not require a battery to back up its data. This saves significant cost and board space. FRAM can be used for storing settings, configuration and device status information. This information can be used later for activities such as resetting the devices, analyzing the status and activating recovery actions. Byte-wise random access makes memory management more efficient.
This high-speed, non-volatile memory runs like a RAM. This gives programmers the flexibility to assign ROM and RAM memory mapping, depending on their needs. End users can program FRAM at the ground level, to customize to their individual preferences. Standalone FRAM allows designers the freedom to explore and employ FRAM in a wide range of designs.

FRAM Based Radio Frequency Identity (RFID) Chip
RFID technology has become an essential way to maintain an audit trail at the item level. The industry is no longer satisfied with the limited information available through magnetic strips or barcodes. Larger amounts of information—including ID, historical records, and tracking records—are required to be stored with each individual product. Traceability at difference stages of the supply chain is essential to ensure quality products and services through monitoring from each process stage. FRAM for RFID is an ideal technology to enable robust tracking applications.

This dual-interface device can be implemented as part of a microcontroller-based embedded system. Data captured by the sensors and the microcontroller can be stored in the FRAM device. The user has easy and convenient access to this data using the contactless UHF interface. Or the user can transfer configuration and control data to the embedded system via the RF field. The dual-interface FRAM is used in applications such as logistic tracking systems, data logging devices, information displays and vending machines.
