Embedded Non-Volatile Memory Solutions Lineup

High Density NVM

We will introduce a technology based on NRAM, which is non-volatile RAM that uses carbon nanotubes.

Next Generation NRAM


  • Random Access
  • Low voltage & low power consumption rewrite
  • High Read/Write Cycle Endurance (even in high temparature)


  • Wearable IoT
  • Automotive (For High tempreture), Replacing EEPROM

High End NVM

We will introduce our technology solutions using ESF3 (Note 1)and FLOTOX
(FLOating gate Tunnel OXide).

Note 1: This product uses SuperFlash® technology licensed from Silicon Storage Technology, Inc.
SuperFlash® is a registered trademark of Silicon Storage Technology, Inc.



  • As 40 nm technology, we use ESF3 from Silicon Storage Technology, Inc. (SST), a high performance, highly integrated, highly reliable technology with a proven record in the market.
  • As 55 nm technology, we offer our original FLOTOX Fash, a highly reliable technology with proven records in the automotive market, which were accumulated since our period as an IDM

    “Fujitsu Semiconductor Successfully Embeds Flash Memory onto DDC™ Technology” »

  • Achieves both a high performance of at least 100 MHz and endurance performance of 100 Kcyc; meets AECQ-100; and guarantees operation at Tj150°C.


  • Automotive, high performance & large-capacity eFlash memory

Middle Range NVM

We will introduce our technology solution, Plug-In Flash.

Plug-in Flash (In-House)


The Plug-In concept enables customers to embed flash memory in their products while making the most of existing design resources.
– Minimize chip cost with sophisticated design integration of processes, devices, and circuits.
– Low-power-consumption data reading and rewriting are implemented using novel circuit technology.


  • Wearable, IoT, Consumer MCU

Low End NVM

We will introduce our technology solutions with non-volatile memory IP.

MTP(Multiple Time Programmable)/OTP(One Time Programmable)


Low cost Non-Volatile Memory that can be manufactured using a standard logic process
– IP support provided by third party vendors


  • Security, Storage of trimming data, Storage of small program files
