Any one know why gertboard ATMEGA losses data on reboot/shutdown?

I have a project where I have data written to the ATmega but it seems whenever it losses power, it loses all data. Could someone explain why? and if possible, a solution.

No idea. I really can't explain that.
I have had a 'complaint' about the opposite: A user who was surprised that his last program started running after power up.
How/where did you place the program and how do you boot?
I am not an expert on the ATmega but it can be programmed to have a boot loader which then
loads and programs the main program. That is how the Arduino works, but not the Gertboard.
For the Gertboard the program has to be the main program and placed from address 0 onwards.
