Nonvolotile EEPROM for configuration parameters

In old good 8-bit Architecture (AVR,PIC,...) CPU had a nonvolatile memory region to keep configuration parameters of the application that were persistent over reset. This region had a byte read/write access without erase requirement.

In STM32 I can not find a substitution to this EEPROM and thus I do not know how to keep my application configurations. Although STM32 Flash can be erased/written it is not acceptable. As to write byte I have to erase and rewrite the whole 16K segment (STM32F2).
All I can think about is to use external I2C or  SPI EEPROM.
Are there any other suggestions?
