Fujitsu Launches 8Mbit Quad SPI FRAM Capable of 54MB/s Data Writing

- Non-volatile Memory IC, Ideal for Industrial High-performance Computing, Achieving High-speed Operation in High-temperature Environments -

Yokohama, Japan, January 18, 2022 – Fujitsu Semiconductor Memory Solution Limited today announced the launch of 8Mbit FRAM MB85RQ8MLX with Quad SPI interface, which is the largest density in Fujitsu’s SPI interface FRAM product family. Evaluation samples are currently available. (Fig.1)

This new product achieves a fast data transfer rate of 54MB per second at maximum 108MHz of operating frequency in high-temperature environments up to 105°C. Featuring high-speed operation and non-volatility, the product is ideal for high-performance computing (HPC), data centers and industrial computing such as programmable logic controllers (PLCs), human machine interface (HMI) and RAID controllers.

The MB85RQ8MLX is a non-volatile memory with 8Mbit memory density and operates at a low power supply voltage from 1.7V to 1.95V. This new Quad SPI interface FRAM achieves 54MB/s data reading/writing speed with four I/O pins and 108MHz operating frequency. It is more than 8 times faster than the other SPI interface FRAM product operating at 50MHz, which transfers data at 6.25MB/s.

In industrial computing, electronic components are required to be guaranteed to operate in high temperature environments as ambient temperatures in computing units increase due to high-speed data processing. This new FRAM has extended the upper limit on the operating temperature range from 85°C of general products to 105°C to satisfy the critical requirement in industrial usage. In addition to this MB85RQ8MLX, the other 8Mbit Quad SPI FRAM product, which operates at power supply voltage from 2.7V to 3.6V, is under development.

The new FRAM, MB85RQ8MLX, does not need any data-backup battery and brings customers using low-power SRAM as a buffer the computing cost benefit of eliminating the battery.

In addition, FRAM is a non-volatile memory product with superior features of fast writing speed, high read/write endurance and low power consumption compared with conventional non-volatile memory such as flash memory and EEPROM. Our FRAM products can solve following issues arising from the use of flash memory, EEPROM, or low-power SRAM. (Fig.3)

Fig.3：Customers’ Issues and Solutions

Case 1: Use of flash memory

• Issue: Large software development burden due to lower write endurance

• Solution: Eliminating the need for developing software for wear leveling development by use of FRAM with high read/write endurance

Case 2: Use of EEPROM

• Issue: Long data-writing time

• Solution: Reducing data-writing time by use of FRAM featuring fast writing operation

Case 3: Use of low-power SRAM

• Issue: Use and extra cost of data-backup battery

• Solution: No use of the battery as FRAM of non-volatile memory provides 54MB/s data transfer speed

With the introduction of MB85RQ8MLX, Fujitsu Semiconductor Memory Solution now has three types of 8Mbit memory products. (Fig.4) Different features are required by customers’ end-products and, having three types of 8Mbit products, we are proud of now being able to serve a wide variety of customer needs.

Fujitsu Semiconductor Memory Solution continues to develop memory products to enhance functions of customers’ end-products.

Glossary and Notes

• * FRAM:

  Ferroelectric Random Access Memory
  Ferroelectric random-access memory. A type of memory that uses a ferroelectric file as capacitors that store data. Retains contents even when power is removed. Combines benefits of both ROM and RAM, with fast write speed, low-power consumption, and high read/write cycle endurance. Also known as FeRAM. Produced by Fujitsu Semiconductor Memory Solution since 1999.
