Standalone FRAM

Standalone FRAM features and benefits

There are various ways to utilize Standalone FRAM products.

Standalone FRAM can be used to replace SRAM + backup battery. The fast write access of FRAM allows the data to be saved at unexpected power loss. This saves significant cost related to battery maintenance and avoids environmental issues of the application system. 

FRAM can be used for storing settings, configuration and device status information. This information can be used later for activities such as resetting the devices, analyzing the status and activating recovery actions. Byte-wise random access makes memory management more efficient.

This high-speed non-volatile memory runs like a RAM. This gives programmers the flexibility to assign ROM and RAM memory mapping, depending on their needs. End users can program FRAM at the ground level, to customize to their individual preferences. Standalone FRAM allows designers the freedom to explore and employ FRAM in a wide range of designs.

For applications with frequent write accesses, FRAM offers the high write endurance to make “wear leveling” redundant. Customers can save software development efforts and reduce the memory density in this way.
