Hi sunshine day,
Those mentioned KEIL information is not 100% suitable for your/this case.
You only need to know: The memory organization of a Flash Device is divided into flash sectors. The Flash Sector is typically a 64 KB memory page and is written cell after cell. The memory cell size depends on the device architecture and is 8-bit wide (byte), 16-bit wide (half word) or 32-bit wide (word). When you want to erase the flash data, you need to erase the whole flash sector at once. Flash Sectors are named Blocks in RL-FlashFS.
