Hi,

After writing data in FLASH using FLASH_ProgramWord(uint32_t Address,uint32_t Data), I can't erase that Address data by using FLASH_ProgarmWord(uint32_t Address,0xFFFFFFFF).

reply me as soon as possible.

I can't erase that Address data by using FLASH_ProgarmWord(uint32_t Address,0xFFFFFFFF).

Because it doesn't work that way, you have to erase a whole SECTOR (16,64 or 128KB depending on the address range).
