EEPROM Emulation

I need to save a table of values in my uPSD 33xx code, and have it persist between resets. The table is fairly simple and is fixed in size. I have read AN2040 regarding EEPROM Emulation in the uSPD. But I don't think I need to implement a scheme that is as complicated as the one described in the app. note, as my table is off fixed size and when it is updated, I will always write the entire table (e.g., a don't need access to individual addresses in the table). Is there any way to implement this in a simple fashion? If so, can you provide an example? Thanks for the help.

If I understand correctly, the table is of fixed size and can be put at a fixed address. I need to read the table into my program whenever the uPSD is started. If any value in the table is changed, I would like to write back the whole table to the same location in flash. The size of the table is constant, and I wish to always have the table at the same address in flash. Thanks.
