    FM25V20A FRAM Test in Production Environment


      I got a question when I try to put a production test plan for FM25V20A FRAM. Our primary use for FRAM is to write in log files and pull to an external device. We are utilizing every cell in FRAM. If I want to test write and read to random memory address on each page of memory, the firmware implementation will be intensive. We have turn off the fire system (in other word, shut off the normal operating system) to do this. So I am seeking advice on how to test FRAM in production environment. Does it have a built-in error correction/check if something is wrong while writing to a memory address? Or, does it have certain failure mode that is necessary to check out before assembly?
