You can't execute AVR code from it but you can store data there.  
Technically, it is possible to copy code from the external device to 
Flash but you probably shouldn't do that due to the write cycle 
limitations.

AT24C256??

I don't understand the question.  The device that you mention has an 
SPI interface.  The A0/A1 lines can be used for selecting among 
multiple devices.
