FRAM Technology

FRAM (Ferroelectric Random Access Memory) is a unique memory solution that combines the best features of RAM and ROM. It significantly outperforms existing non-volatile memories like E2PROM and Flash.

FRAM is a type of non-volatile RAM that uses a ferroelectric film as a capacitor to store data. In contrast to the conventional non-volatile memories like Flash and E2PROM, the content of an FRAM cell is not stored in the form of charge carriers in a ‘floating gate’. The information – logically 0 or 1 – is contained in the polarization of the ferroelectric material lead zirconate titanate, PZT (Pb (ZrTi)O3). This material is placed between two electrodes in the form of a thin film, in a similar way as the structure of a capacitor.

Crystal structure

By generating an electric field between the two electrodes, the ferroelectric film will be polarized, instead of moving charges from one electrode to the other. Because the polarization remains after the electric field is removed, the content of the FRAM remains in absence of power. This non-volatility represents the major advantage of FRAM compared to DRAM.

Product features include:

  • fast overwrite speed (30,000 times faster than EEPROM)
  • high endurance (up to 10 trillion read/write cycles)
  • low power consumption
  • tamper resistance
  • higher resistance to radiation than flash and EERPOM
  • higher resistance to magnetic fields than MRAM
FRAM benefits

Application features include:

  • real time logging/monitoring possible
  • simplification of system architecture by replacing RAM/ROM operations with FRAM
  • reduced error sources in a simplified system
  • extend/ensure battery lifetime
  • increase/ensure data security and integrity
