some micros support IAP- In Application Programming, which can be used to store variables or modify code without using external EEPROM or NVRAM. Ds89C4x0 is one such micro which supports this. usually there is a upper bank flash memory and lower bank memory, the contents of lower bank cannot be changed and only contents of upper code memory can be altered by the program. and when writing new variables the whole upper bank block has to be erased.
