We are mass-producing the 4Mbit FeRAM MB85RQ4ML featuring fast data transfer. This non-volatile memory can achieve data transfer rate of 54MByte per second at maximum 108MHz of operating frequency and a Quad SPI interface with four I/O pins. (Fig.1)
With features of high-speed operation and non-volatility, this product makes it ideal for use in the industrial computing and networking devices such as programmable logic controllers(PLCs) and routers requiring fast data rewriting. (Fig.2)

Fig.2: Suitable Usage (PLC, Router)For over 20 years, we have mass-produced FeRAM products featuring higher read/write endurance, faster writing speed operation and lower power consumption compared to EEPROM and flash memory. So far these high reliable products have been successfully adopted in industrial, infrastructure, consumer, and automotive fields.
In addition, some customers have been requesting for FeRAM that can operate with fast data transfer while being non-volatile memory. We were pleased to be able to fulfill this requirement with the Quad SPI 4Mbit FeRAM product.
This product adopts a Quad SPI interface and 1.8V power supply voltage and it is capable data transfer rate of 54MB/s at operating frequency of 108MHz. Until the release of this product, 4Mbit FeRAM with parallel interface of 16 I/O pins is the fastest FeRAM having 13MB/s data transfer.
However, the MB85RQ4ML with only four I/O pins enables to read and write the data in about 4 times of that of parallel interface FeRAM. (Fig.3) Its package is 16pin SOP in 7.5mm x 10.3mm package size.
