Saving data to non-volatile on chip memory.

Greetings,

I am a newbie and started to learn 89s8253 micro processor. So far i have written c code for Modbus Slave. I am storing the device id in idata variable but the value is lost on power off.

Please guide me how to store the value on on-chip memory so that it is retained even on power off.
