I am using STM32F405 as the controller in my project. We have hundreds parameters needed to be saved in the Flash memory and this parameters will be modified one by one during the running. The problem is the flash memory must be erased by section and rewrite the whole section even if we just want to change one byte in the memory. It takes long time and has to stop the access the all parameters during the updating. 
Is there fast method that we can overwrite the one byte/ byte?
