unwanted erase in UFM

hi everyone, I'm working on a custom board. There is a Max2 on it and I store the serial number of our device in the UFM. Once, one of our customer power down the device and power up again...

I use parallel Mode, and I meet the same question, the UFM is erased when our board power down and power up again even if I always force the erase signal to VCC.
