Non-volatile memory with high operational speed that contributes to improving the performance of network devices
Yokohama, Japan, February 18, 2016 – Fujitsu Semiconductor Limited today announced the development of MB85RQ4ML, its new FRAM product with 4 Mbit of memory, which represents the highest density in the non-volatile RAM market with a quad SPI interface. The new product is available in sample quantities starting today.
This product operates with a 1.8V single power supply, using a quad SPI interface with four I/O pins, and can achieve data transfer rate of 54 MByte per second.
Its high-speed operation and non-volatile memory make it ideal for use in the networking, RAID controller, and industrial computing fields.
Leveraging FRAM's non-volatility, high-speed read/write cycles, high read/write endurance, and low power consumption, Fujitsu Semiconductor has been proposing batteryless solutions using FRAM for the wearables market and the IoT market.
In response to rising demand for faster speed in non-volatile RAM interfaces, Fujitsu Semiconductor has now developed the MB85RQ4ML 4Mbit FRAM, which has the highest data transfer rate in its FRAM product line (figure 1).
This product uses a 1.8V single power supply and quad SPI interface, and is capable of 54 MB/s data transfer with 108 MHz operation. Among Fujitsu Semiconductor's previous products,
4Mbit FRAM with 16-bit parallel interfaces in 44-pin TSOP package was the fastest at 13 MB/s, however this product enables approximately 4 times the data read/write speed with less pin counts (figure 2).
This product is an ideal for network equipment, such as routers, where setting data values is continually rewritten. It is positioned half-way between high-density non-volatile memory for data storage and high-speed working memory, and supports data rewriting with high-speed access and data back-ups (figure 3).
In the IoT market, which handles with big data, data processing volumes are increasing, and there is a need for frequent data rewriting in memory. In addition, from a security perspective, greater importance is being placed on preserving access records. Considering this background, as the memory that preserves access information in the networking field, this product contributes to improving equipment performances.
Fujitsu Semiconductor will continue to provide products and solutions to increase the value and convenience of customer applications.
