What is the function of the memory OTP area in STM32?When do we use the memory OTP area?

Serial numbers, encryption keys, calibration or manufacturing data, etc

Actually I think it can be ''modified'' in that any ONE bits can be changed to ZERO bits, but you can't erase it, and you can't reprogram it with arbitrary bytes. You could checksum/crc the area, or write a byte, and it's inverse.
