I cannot edit the program or replace the hardware.Is there in hardware solution to make it write protect on the fly (may shorting pins ). thanks rutu

Some serial EEPROM devices have a hardware write protect pin (or write enable), that when connected either high or low will do what you need. You'll need to read the datasheet for your particular device to see if it supports this. Why do people insist on not looking at the datasheets for their hardware?? Or is this an assignment?

Or is this an assignment?" Why should it be any different for an assignment? [rhetorical] Don't they teach students the importance of reading datasheets? [/rhetorical]
