Hi I am using the AT89C51ED2 in my project and I am using it's internal EEPROM. When I write data in the internal eeprom and read the data back the program is working well. But when I remove the supply and try to read back the data, It don't give me the data written later. It is written on the data sheet that it is a non volatile memory which that means that the data stored in the eeprom is stored even if the supply is turned off. Am I wright?
