FRAM Advantage

What is FRAM?
FRAM (Ferroelectric Random Access Memory) is a non-volatile memory combining both ROM and RAM advantages in addition to non-volatility features. Its higher speed in write mode, its lower power consumption as well as its higher endurance, make FRAM superior to any other memory type. As a high-speed non-volatile memory, FRAM can be used in the wide range of offerings.

FRAM Benefits

  • High speed
  • High security
  • Low power consumption
  • Minimum 10 year data retention
  • High endurance of minimum 10E10
  • Random access
  • Byte access
  • Low cell internal voltage of 5G for 0.5um and 3.3V for 0.35um
  • No need for booster circuit for voltage matching with CMOS

FRAM™ Advantages over EEPROM

1. Transaction Time:

- 30,000 times faster than EEROM
- 1kByte R/W as a general use in
transportation (contact-less cards)
2. Energy Consumption:

- 100,000 times higher endurance over EEPROM
- Energy Consumption @64Byte Write Cycle
3. Endurance:

- 200 times lower power consumption compare to
EEPROM
- 1 FRAM Cycle: Read
- 1 E2PROM Cycle: Erase/Write/Read
