STK14CA8-N25I Memory disruption
I have a table stored in part of the STK14CA8-N25I nvSRAM. This table is stored first time at the production line at the begining of the product life. The table is NOT supposed to be updated during the unit life cycle. Every power-up the table is being read from the memory and used by the product functionality.
Unfortunately, in several units the table was disrupted and few bits, in random places, changes their value from '0' to '1'. (The memory nas NOT erased or "run over", just disrupted in some random bits).
It sounds very similar to the Single Enent Upset (SEU) described in AN15979 but it occurs too much frequent.
Have you meet this phenomena before in nvSRAM devices ? do you have recomandations how to solve this memory disruption ?
