FUJITSU has been offering the high quality and high performance memory, which are essential for enhanced digital applications, over many years. In addition to offering memory products for the greater miniaturization, higher performance, and lower power consumption in recent years, our company also proposes the best solutions combined with memory.

System Memory


FRAM FRAM (Ferroelectric Random Access Memory) is one type of non-volatile memory. As compared with conventional types of non-volatile memory, such as EEPROM (Electrically Erasable and Programmable Read-Only Memory) and Flash memory, FRAM exhibits superior performance through faster write speeds, greater read/write cycle endurance and lower power consumption. Fujitsu Semiconductor has been providing FRAM to the card, industrial, and medical fields, besides, in recent years its use has expanded to IoT applications, such as wearable devices, robots, and drones.


ReRAM (Resistive Random Access Memory) is a type of non-volatile memory.
Since the current in read is extremely low, it is ideal for compact devices such as battery-powered wearable devices and hearing aids.


NRAM is non-volatile memory utilizing a new technology called carbon nanotubes. It has expected as new non-volatile memory featuring greater read/write endurance, lower power consumption, and faster write speeds, with large memory density.
