You add an EEPROM or flash or MRAM or some other form of
non-volatile storage.

Don't they have flash either?

Probably.

Some ARMs with on-chip flash are self-programming. You can use a spare
flash sector to store your nonvolatile data. Otherwise, add an I2C or
SPI EEPROM.

I have experience developing 8051 but I'm very new to ARM comparing to
AVR.

My question is how ARM save data since it doesn't have built in eeprom
like AVR?  I checked many ARM eval board but they all don't have external
eeprom.

I found a ARM board that completely suit my needs but it doesn't have
eeprom.
I would think this is normal to every ARM and am I missing something?

thanks for any help.
