  Can you guys give me some pointers as I havent done something like

 It all depends how much data you need to store. 16 kB or less, use an
I2C or SPI EEPROM from uchip or xicor. Up to 512 kB use a NS  NM29A040
with microwire and above that a NAND flash f.ex NM29N16 with a byte
serial i/f.
A 16C63 will be a perfect choice. NS has several  appnotes how to use
and interface these chips theat you could get from www.ns.com
