One confusing aspect of STM32 is that the flash layout differ greatly between families and even individual MCUs within a family. On some families flash can be erased by page - typically 1 KB or 2 KB. On others erase can only be done per sector and the sectors are not of the same size. The information is in the reference manual of each MCU.
