2 wire (I2C) is probably the easiest way. 
You get two different addressing schemes : 
1) 7 bit (generally for sizes up to 16k bits)
2) 10 bit (generally for sizes 16k bit - 256k bit)

You have to implement the master mode in software to talk 
to the memory chips.
Get the Phillips (I2C patent holder) specification. There 
is a link from my web page as well as other I2C resources.
